1f818b09f8 ramips: add proper system clock and reset driver support for legacy SoCs
This series of upstream patches properly implement a clock and reset
driver for old ralink SoCs[1]. And it includes some related fixes[2] and
improvements[3][4]. All patches have been merged into linux-next. They
will be part of upcoming Linux 6.5. In order to switch to the new system
controller driver, all clocks and resets properties in SoC dtsi have been
updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the
kernel config files.

kernel: disable CONFIG_CPU_LITTLE_ENDIAN in generic config
Endianness depends on CPU architecture. CONFIG_CPU_(BIG/LITTLE)_ENDIAN should
be enabled on target or subtarget based on SoC architecture.

Fixes warning:
$ make kernel_oldconfig CONFIG_TARGET=subtarget
...
.config:1008:warning: override: CPU_LITTLE_ENDIAN changes choice state
....

Summary:
- ARC - only the CONFIG_CPU_BIG_ENDIAN symbol is defined for this architeture.
  If it is disabled then the processor operates in LITTLE_ENDIAN mode (default),
- ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This
  option should be enabled after OpenWRT moves to kernel 6.x. After refreshing
  the kernel, the symbol disappears,
- ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN,
- MIPS - enabled relevant symbols,
- POWERPC -  enabled CONFIG_CPU_BIG_ENDIAN,
- UML - Symbols are not defined for this architecture,
- X86 - always little endian. Symbols are not defined for this architecture.

b201462c89 ramips: 5.15: add disabled PINCTRL_AW9523
Otherwise kernel 5.15 will fail to build on subtargets except for mt7621
that has enabled the config.
The disabled PINCTRL_AW9523 config disappears after a refresh, it needs
to be added back manually.
