UART pins (TX, RX, RTS, CTS) are now configured in DTS files.
RTS and CTS definitions are optional. If flow control is enabled
and RTS/CTS pins are not defined, then compiler will issue

A bootloader may leave primask or faultmask set, so clear them during
startup when we enable interrupts and switch to the main thread.
Previously we only cleared primask for architecture variants which don't
support basepri, but now we do it for all architecture variants.
Fixes a failure on mimxrt1050_evk with the latency_measure test and
shell_module sample when using an nxp internal bootloader.

_k_syscall_table is an array of function pointers and is declared as
such in C sources, this makes it an STT_OBJECT[0] in the symbol
table. But when the same symbol is declared in assembly, it is
declared to be a function, which would make the symbol an STT_FUNC.
When linking with LTO this type inconsistency results in the warning:
real-ld: Warning: type of symbol `_k_syscall_table' changed from 2 to
1 in /tmp/cc84ofK0.ltrans8.ltrans.o
To fix this warning we declare the table with GDATA instead of GTEXT,
which will change the type from 'function' to 'object'.

This commit refactors the _get_region_attr_by_conf(.) function,
so it does the following:
- it is renamed to _get_ram_region_attr_by_conf(), to reflect
that it is only used to configure RAM MPU regions.
- it gets an arm_mpu_region_attr_t object structure pointer
to fill-in with the derived region attributes.
- it takes an additional argument (the region base address),
which allows the function to have a common signature with the
ARMv8-M version of it (where the attribute derivation needs
the base address).

This commit refactors the _get_region_attr_by_type(.) function,
so it does the following:
- it takes an arm_mpu_region_attr_t object pointer and use it
to fill-in the derived region attributes.
- it performs only the distinguishing between the different MPU
region types, hiding the actual MPU-specific implementation
in internal functions.
- it takes an additional argument (the region base address),
which allows the function to have a common signature with the
ARMv8-M version of it (where the attribute derivation needs
the base address).
- it returs 0 or succes and a negative non-zero integer
to indicate an error.

There exist two symbols that became equivalent when PR #9383 was
merged; _SYSCALL_LIMIT and K_SYSCALL_LIMIT. This patch deprecates the
redundant _SYSCALL_LIMIT symbol.
_SYSCALL_LIMIT was initally introduced because before PR #9383 was
merged K_SYSCALL_LIMIT was an enum, which couldn't be included into
assembly files. PR #9383 converted it into a define, which can be
included into assembly files, making _SYSCALL_LIMIT redundant.
Likewise for _SYSCALL_BAD.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

A design flaw of 'gsource' is that there's no way to require at least
one file to match the glob pattern. This could lead to silent errors.
Switch to a new design, where a plain 'source' is globbing and requires
at least one file to match. A separate 'osource' (optional source)
statement is available for cases where it's okay for a pattern (or plain
filename) to not match any files.
'orsource' combines 'osource' and 'rsource' (relative source).
This commit search-replaces 'gsource' with 'source', but backwards
compatibility with 'gsource' is still maintained by making it an alias
for 'osource' (and by making 'grsource' an alias for 'orsource').
The three Kconfig files arch/{nios2,posix,xtensa}/Kconfig source
arch/{nios2,posix,xtensa}/soc/*/Kconfig, which doesn't match any files.
Use 'osource' for those. The soc/*/Kconfig files seem to be for
additional SoC-specific symbols, only none exist yet on those ARCHes.
Also use 'osource' for the source of $ENV_VAR_BOARD_DIR/Kconfig in
boards/Kconfig, which doesn't exist for all boards.
