Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.
Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
will be 'constified')
It also generate a tiny memory gain on both ROM and RAM, which is nice.
Perhaps kernel/device.c could be renamed to something more relevant.

This commit cleans up the section name definitions in the linker
sections header file (`include/linker/sections.h`) to have the uniform
format of `_(SECTION)_SECTION_NAME`.
In addition, the scope of the short section reference aliases (e.g.
`TEXT`, `DATA`, `BSS`) are now limited to the ASM code, as they are
currently used (and intended to be used) only by the ASM code to
specify the target section for functions and variables, and these short
names can cause name conflicts with the symbols used in the C code.

sw_isr_table has two entries, an argument and an ISR function. The
comment on struct _isr_table_entry in include/sw_isr_table.h says that
"This allows a table entry to be loaded [...] with one ldmia
instruction, on ARM [...]". Some arch, e.g. SPARC, also has a double
word load instruction, "ldd", but the instruct must have address align
to double word or 8 bytes.

architecture to specify it, if needed. The default value is 0 for no

changed SETTINGS_REGISTER_STATIC() to SETTINGS_STATIC_HANDLER_DEFINE()
changed settings_handler_stat type to settings_handler_static type
removed NULL declarations
renamed bt_handler to bt_settingshandler, as bt_handler already exists.
renamed all bt_XXX_handler to bt_xxx_settingshandler to avoid any

Add the possibility to register handles to ROM using a new macro
SETTINGS_REGISTER_STATIC(handler), the handler is of type
settings_handler_stat and has to be declared as const:
```
const struct settings_handler_stat test_handler = {
.name = "test", /* this can also be "ps/data"
.h_get = get,
.h_set = set,
.h_commit = NULL, /* NULL defines can be ommited */
.h_export = NULL /* NULL defines can be ommited */
};
SETTINGS_REGISTER_STATIC(test_handler);
```
To maintain support for handlers stored in RAM (dynamic handlers)
`CONFIG_SETTINGS_DYNAMIC_HANDLERS`must be enabled, which is by default.
When registering static handlers there is no check if this handler has
been registered earlier, the latest registered static handler will be
considered valid for any set/get routine, while the commit and export
routines will be executed for both registered handlers.
When a dynamic handler is registered a check is done to see if there was
an earlier registration of the name as a static or dynamic handler
registration will fail.
To get to the lowest possible RAM usage it is advised to set
`CONFIG_SETTINGS_DYNAMIC_HANDLERS=n`.
Updates:
a. Changed usage of RAM to DYNAMIC/dynamic, ROM to STATIC/static
b. Updated settings.h to remove added #if defined()
c. Make static handlers always enabled
d. Corrected error introduced in common-rom.ld.
e. Changed return value of settings_parse_and_lookup to
settings_handler_stat type to reduce stack usage.
f. Updated the name generated to store a handler item in ROM. It now
uses the name used to register in combination with the line where
SETTINGS_REGISTER_STATIC() is called.
g. renamed settings_handler_stat type to settings_handler_static
h. renamed SETTINGS_REGISTER_STATIC to SETTINGS_STATIC_HANDLER_DEFINE()

This convenience macro wraps Z_DECL_ALIGN() and __in_section() to
simplify static definitions of structure instances gathered in dedicated
sections. Most of the time those go together, and the section name is
already closely related to the struct type, so abstracting things behind

clearer. A few input section names have been adjusted accordingly.

If CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT is enabled,
the app shared memory partition may cause waste of memory
due to the need for padding.
For example, tests/subsys/jwt and board mps2_an385:
z_test_mem_partition: addr 0x20000000, size 52
z_libc_partition : addr 0x20000040, size 4
k_mbedtls_partition : addr 0x20008000, size 32736
ending at 0x2000ffff, taking up 65536 bytes
With power-of-two size and alignment requirement,
k_mbedtls_partition takes up 32KB memory and needs to be
aligned on 32KB boundary. If the above partitions are
ordered as shown, there needs to be a lot of padding
after z_libc_partition before k_mbedtls_partition can
start. In order to minimize padding, these partitions
need to be sort by size in descending order.
After the changes here, the partitions are:
k_mbedtls_partition : addr 0x20000000, size 32736
z_test_mem_partition: addr 0x20008000, size 52
z_libc_partition : addr 0x20008040, size 4
ending at 0x2000805f, taking up 32864 bytes
With the above example, sorting results in a saving
of 32672 bytes of saving.
