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.

treewide: remove files for building 5.10 kernel
All targets are bumped to 5.15. Remove the old 5.10 patches, configs
and files using:

  find target/linux -iname '*-5.10' -exec rm -r {} \;

Further, remove the 5.10 include.

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.

afcb6b1524 armvirt: 64: enable driver for QEMU' supported watchdog
QEMU can emulate several watchdogs:
aspeed SoC, i6300esb, ib700wdt, imx2, cmsdk-apb and sbsa_gwdt.

Out of these, the ARM SBSA Generic Watchdog (sbsa_gwdt)
makes the most sense for the armvirt' 64 target. Both imx2 and
aspeed are guarded by special vendor specific CONFIG_ in the
upstream kernel.

either directly required for mac80211 crypto support, or directly
selected by such options. Support for the mac80211 crypto was enabled in
the generic config since c7182123b9 ("kernel: make cryptoapi support
needed by mac80211 built-in"). So move the above options from the target
configs to the generic config to make it clear why do we need them.

222dc0ad91 armvirt/64: change it to cortex-a53 instead of generic
Package architecture aarch64_generic [1] can be used just with three
devices. One is NanoPI R2S and then there are two development boards
from NXP. Let's change armvirt/64 to Cortex A53 (aarch64_cortex-a53)
[2]. It has wider support by multiple devices like NanoPI Neo Plus2/Core2,
ESPRESSObin, Pine64, and Raspberry Pi 2&3.

While looking at ARMvirt/32 it has set CPU_TYPE and CPU_SUBTYPE to be
arm_cortex-a15_neon-vfpv4 [3]. It has support to devices like
Linksys EA8500 v1, Linksys EA7500 v1, Netgear D7800, Netgear R7500 and so on.

Tested with:
qemu-system-aarch64 -m 1024 -smp 2 -cpu cortex-a57 -M virt -nographic \
-kernel openwrt-armvirt-64-Image-initramfs

Successfully compiled and booted.
Here goes the output:

46af22de16 kernel: Remove CONFIG_COMPAT
This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.

This reduces the attack surface on such systems and should also save
some memory.
