9e348da477 kernel/sunxi: Restore kernel files for v6.1
This is an automatically generated commit which aids following Kernel patch history,
as git will see the move and copy as a rename thus defeating the purpose.

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.

a98ded6c5c kernel: move some symbols to generic config
This commit add some enabled symbols to generic config.
LTO is only supported by clang compiler and therefore should
be disabled in the generic config instead of duplicating this
symbol in each target. CONFIG_LTO_NONE do this job.

The second group of symbols is enabled by the options available
in the generic config and is therefore added here:
* CONFIG_AF_UNIX_OOB is selected by CONFIG_NET && CONFIG_UNIX,
* CONFIG_BINARY_PRINTF is selected by CONFIG_BPF_SYSCALL,
* CONFIG_NET_SOCK_MSG is selected by CONFIG_BPF_SYSCALL && CONFIG_NET.

The other symbols are disabled and should be in the generic config.

This commit also removes these symbols from subtargets.

  LED: WAN, LAN, SYS
  KEY: Reset
  Power Supply: DC 5V/2A

Installation:
  Write the image to SD Card with dd.

Note:
  1. OpenWrt currently does not support LED_FUNCTION, change back to the
     previous practice (Consistent with NanoPi R1).
  2. Since the upstream commit https://github.com/torvalds/linux/bbc4d71
     ("net: phy: realtek: fix rtl8211e rx/tx delay config"), we need to
     change the phy-mode from rgmii to rgmii-id.

78c1ed64fa sunxi: enable MUSB in A53 subtarget
The Pine64(+) and the SoPine64 baseboard has two USB ports. One of
these (the lower) is connected directly to a USB host, the other
one's (upper) PHY is shared with the separate OTG controller. In
order to get it working, MUSB support needs to be enabled.

As there are other targets which compile MUSB support into the kernel
and not package it into modules, the same is done here.

The Orange Pi Zero Plus uses a RTL8211E, add the driver for this PHY.
This is probably used on more boards with a Allwinner SoC.

This is based on the code for kernel 4.9, but a lot of 4.9 patches are
backports from more recent kernel version and can be removed now.

8b35da1552 kernel: move CONFIG_KASAN to generic config
While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN
symbol. Move it to generic config instead of defining it for all arm64
and x86/64 targets.

It was only added in 4.0, so not needed in config-3.18.
