Kconfig symbols CONFIG_ARM64_CNP and CONFIG_ARM64_EPAN got exposed
by enabling CONFIG_ARM64_PAN. Enable them as well, as just like for
PAN, also EPAN and CNP will be detected at runtime at no cost.

Enable the CONFIG_ARM64_PAN kernel security option, which leverages the
ARMv8.1 Privileged Access Never (PAN) extension to prevent the kernel
from directly accessing user space memory.
Instead, copy_to_user and similar functions must be used for data
transfer between kernel and user space. This feature is automatically
disabled at runtime on CPUs without PAN support, making it a no-op in
those cases.

This reverts commit f98f95359b.
It seems that this commit is causing issues with the PWM fan on the RPi 5 as
reported here: https://github.com/openwrt/openwrt/issues/16191
So let's revert this for now.

- Enable CONFIG_HWMON and CONFIG_THERMAL_HWMON on all subtargets.
- Drop kmod-thermal from bcm2712.
- Add CONFIG_SENSORS_RASPBERRYPI_HWMON generic symbol.

This is preparation for 6.6 kernel support. Copying files makes it easier to
track their git history.

Sync 6.1 patches with the RPi foundation.
Since rpi-6.6.y is now the main branch of the RPi foundation, there won't be
any new patches for linux 6.1.

This patch adds support for Raspberry Pi 5.
Instead of using 16K pages like Raspberry Pi OS, OpenWrt uses 4K pages due to
incompatibilities with F2FS and other applications.
There are multiple RPi forum posts with different cases and users are forcing
kernel8.img to workaround them, which is the 64 bit kernel of the RPi 4.
However, this isn't possible in OpenWrt because we only ship one kernel and we
would have to add RPi 5 support to bcm2711 subtarget (RPi 4) for that
workaround to work in OpenWrt.
