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.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

This deactivates the CONFIG_COMPAT kernel option.
With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32
binaries in addition to the interfaces needed for arm64 binaries.
In OpenWrt the complete userspace is compiled for this specific
architecture and support for 32 bit ARM applications is not needed.
This reduces the size and the attack surface for the systems.
On all other targets CONFIG_COMPAT is already deactivated.

This activates the CONFIG_ARM64_SW_TTBR0_PAN option for all arm64
kernels by default.
The CONFIG_ARM64_SW_TTBR0_PAN option prevents the kernel form accessing
user space memory directly. This makes it harder to exploit the kernel.
This is activated by default and was already activate on all other arm64
targets before.

MT7981 and the upcoming MT7988 have built-in Gigabit Ethernet PHYs.
While they share some design properties with the PHYs present in
MT753x, they do need calibration data from the SoC's efuse.
Add driver to support them. Upstreaming it is planned, but there are
still some ongoing discussions with MediaTek.

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.

The most common CPU governor in the OpenWRT project is currently ondemand (see
below). Switch mt7622 over to it as well.

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.
