5a4389f6ab bcm27xx: 5.15: turn on cpu erratum for A72 and disable A53
The original configuration might be copied from bcm2710 which uses
cortex A53 rather than A72 in BCM2711, without errata might be harmful
to system stability and security.

5df84814bb kernel: enable (ARM|ARM64)_MODULE_PLTS in generic config
This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.

The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

3f7cc9d014 bcm27xx: disable duplicate sdhost driver
Enabling both CONFIG_MMC_BCM2835 and CONFIG_MMC_BCM2835_SDHOST causes this
error in dmesg:
Error: Driver 'sdhost-bcm2835' is already registered, aborting...

Disabling CONFIG_MMC_BCM2835 and leaving CONFIG_MMC_BCM2835_SDHOST enabled
avoids this error.

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.
