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.

The NanoPi R2C is a minor variant of NanoPi R2S with the on-board NIC
chip changed from rtl8211e to yt8521s, and otherwise identical to R2S.

The bootscript for nanopi r2s/r4s only changes the serial address, so
make it auto detected in mmc bootscript rather than creating more
(redudant) files.

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.

The previously stated speed of sdr-104 in is too high for the hardware
to reliably communicate with some fast SD cards.
Rockchip boards have a common bug when operating uhs speed, which will
hang the system during a soft reboot.
To be on the safe side, lower the speed to workaround.

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

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.

The legacy (BSD) PTY support could open security problems in a system,
We do not need them in OpenWrt, deactivate this option in all targets.
Debian also deactivates this option.

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.

This activates CONFIG_HARDENED_USERCOPY for the remaining targets. This
adds additional checks in the copy_from_user() and copy_to_user()
functions.
This was not activated for ARCHS38 before because of a bug in the Linux
kernel 5.4 till 5.14, which as fixed and is described here:
https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/15
I do not know why this was deactivated for mt7629 and rockchip.
