Move the `pm_device_runtime_init_*` functions from <pm/device_runtime.h>
to <pm/device.h>. The initial device state should be settable
independently of whether `CONFIG_PM_DEVICE_RUNTIME` is enabled.
This also resolves a compilation error when attempting to use these
functions without also including <pm/device.h>.
Function documentation is also updated to be more general than only
referencing runtime PM, as this also applies to system PM and manually
run actions.

It can be useful to know what a node's index is in its parent's list
of children. This information is now available to C via
gen_defines.py, but no user-facing macros are available to access it.
Add a macro which exposes this information to users via devicetree.h.
Some APIs want to build on devicetree.h by creating some derived
structure for each of a node's children. It can therefore be
convenient to use each child's index in the list of children as an
identifier for the child.
Some concrete and common examples are "gpio-keys" and "gpio-leds",
which allow you to define arbitrary numbers of keys and LEDs as child
nodes of nodes with those compatibles. Derived APIs can use a key or
LED node's index in its list of parents as a way to identify which of
several structures is relevant to a particular controlled key or LED.
These are just examples, though -- the feature added here makes no
assumptions about where it's being used.

In addition to x86-32, POSIX boards are also affected by the issue
where a `long double` has the size of 12.
Simplify the process by setting the alignment to 16 for xtensa (as
before). Then defaulting to using `long double` if the config is set.
The case of 12 byte `long double` is then handled by Z_POW2_CEIL when
available. Otherwise, a BUILD_ASSERT is used to verify that alignment
is valid.

So far the I2C channel connected to the battery has chosen the option
of Standard-mode 100KHz, but according to the SI(Signal Integrity)
test report, the I2C channel doesn’t meet the tHD;DAT Margin/Threshold
in the SI test. In fact, the timing could be adjusted by changing the
settings in the related timing registers in EC, but unfortunately the
limitation exists due to the fact that the timing registers have been
currently occupied by another channel for the same reason, that is,
adjusting the timing.
However, according to the I2C specification, the Standard-mode (Sm)
has a bit rate up to 100 kbit/s, so far the battery use the option
of standard mode 100KHz in the SMCLK setting register. This SMCLK
setting register also provides standard mode 50KHz for usage.
According to another SI test reports, so far the Standard-mode 50KHz
setting looks good in the SI test.
Therefore, add a #define I2C_SPEED_DT allows the device tree to
write a specified speed without causing i2c_configure() and
i2c_get_config() to return error.

The temp val should be uint64_t in read_sysreg64 instead of uint32_t.
The incorrect type uint32_t will cause an issue:
mrrc instruction needs 2 registers when reading from a 64-bit system
register. The type uint32_t tells GCC only to save/restore one register,
so after the mrrc is executed, the other would clash.

This is painful. There is no way for u-mode code to know if we're
currently executing in u-mode without generating a fault, besides
stealing a general purpose register away from the standard ABI
that is. And a global variable doesn't work on SMP as this must be
per-CPU and we could be migrated to another CPU just at the right
moment to peek at the wrong CPU variable (and u-mode can't disable
preemption either).
So, given that we'll have to pay the price of an exception entry
anyway, let's at least make it free to privileged threads by using
the mscratch register as the non-user context indicator (it must
be zero in m-mode for exception entry to work properly). In the
case of u-mode we'll simulate a proper return value in the
exception trap code. Let's settle on the return value in t0
and omit the volatile to give the compiler a chance to cache
the result.

The minimum stack alignment is 16. Therefore, the stack space to store
a struct __esf object must be rounded up to the next 16-byte boundary.
It is not sufficient to do the rounding on the __z_arch_esf_t_SIZEOF
definition. When the stack is constructed in arch_new_thread() it is
also necessary to do the rounding there too.
Let's make the structure itself carry the alignment attribute instead to
make it work in all cases.
While at it, remove the unused _K_THREAD_NO_FLOAT_SIZEOF definition.

Same rationale as preceding commit. Let's create pseudo-instructions in
assembly scope to make the code more uniform and readable.
Furthermore the definition of COPY_ESF_FP() was wrong as the width of
floating point registers vary not according to CONFIG_64BIT but
CONFIG_CPU_HAS_FPU_DOUBLE_PRECISION. It is therefore wrong to use
lr/sr (previously RV_OP_LOADREG/RV_OP_STOREREG) and a regular temporary
register to transfer such content.
Note: There are far more efficient ways to copy FP context around but
such optimisations will come separately.

Those are prominent enough that having RV_OP_LOADREG and RV_OP_STOREREG
shouting at you all over the place is rather unpleasant and bad taste.
Let's create pseudo-instructions of our own with assembler macros
rather than preprocessor defines and only in assembly scope.
This makes the asm code way more uniform and readable.

Currently when a node has a 'zephyr,memory-region' compatible and a
'zephyr,memory-region' string property, a new memory region is created
in the linker script.
Having a memory region without a section to place variables in could be
not that useful. With this patch we extend the memory-region mechanism
to also create sections.
The user can then place variables in the sections as usual by using for
example the GCC attributes.
