Fixes#2349. Patches refreshed because some didn't apply when I built
directly from local repo and tried to import them with "git am".
Known issue: NetworkManager fails to assign IP to usb0, I had to
assign it manually to use USB networking.
This allows use of some USB peripherals that
utilize the CP210X serial chip.
This includes not only mere UART-to-USB adapters,
but also some devices like GPS, Zigbee dongles,
etc.

This kernel release incorporates the following fix from Megi:
- fixed regression in Pinephone power consumption during sleep (touchscreen
was not disabled properly, consuming a lot of power)

-Removed 0013-media-ov5640-Update-last-busy-timestamp-to-reset-aut.patch:
Fix should now be incorporated in 6.3 kernel.

Enable options required for the Android 11 image inside waydroid:
* CONFIG_BPF_SYSCALL
* CONFIG_CGROUP_BPF
* CONFIG_PSI (already set for this kernel)
* not CONFIG_PSI_DEFAULT_DISABLED (already set for this kernel)
The same will be done for all devices in main and community in the
following patches. Also add V=1 for all kernels I'm modifying that are
below 6.2 (see issue 1990).
Kernel configuration addition:
Just like on the PinePhone Pro I enabled the newly added Lazy RCU scheduler.
RCU_LAZY can help battery-powered systems like the PinePhone Pro in a few ways:
1. Reduced CPU usage: Because RCU_LAZY allows readers to access shared data structures without acquiring locks or other synchronization primitives,
it reduces the amount of CPU time that is required to manage synchronization. This can be particularly beneficial in battery-powered systems,
where reducing CPU usage can extend battery life.
2. Reduced memory usage: RCU_LAZY delays the creation of multiple versions of the shared data structure until they are actually needed.
This reduces the amount of memory that is required to store these versions.
In battery-powered systems, where memory usage can be a critical resource, this can help to conserve power.
3. Reduced synchronization overhead: RCU_LAZY reduces the overhead of synchronization by delaying the creation of multiple versions of the shared data structure.
This can reduce the amount of time that is spent acquiring and releasing locks or other synchronization primitives,
which can help to conserve power in battery-powered systems.

This enables the DRAM frequency stats driver that can be useful for debugging
issues with the PinePhone. This came up in a discussion in #pinephone on IRC
where megi was helping a pmos user with idle power draw issues.
This also enables the performance, powersave and userspace devfreq governors.

This solves bug of taking greenish pictures with Megapixels, due to
sensor being shutdown to early after taking a picture.

Schedutil is a CPU scheduler that is designed to be more efficient than other schedulers, such as the conservative scheduler, in terms of energy consumption.
This is because schedutil uses information about the utilization of individual CPU cores to make more intelligent decisions about when and how to scale the frequency of the CPU.
This can help to reduce the overall power consumption of the device, which can be particularly beneficial for battery-powered devices.
Additionally, schedutil can also help to improve the overall performance of the device by ensuring that the CPU is able to operate at its maximum frequency when needed.
In my personal testing I haven't seen any noticable impact on power consumption, while the performance does certainly noticeably increase
Note: This is only a change in the aarch64 configuration as the armv7 configuration already used the schedutil scheduler as default.

Kernel source updated to 6.1-rc7
Ext2 and Ext3 modules in aarch64 config disabled because Ext4 is backwards compatible.
2 fixes for PinePhone included in this source:
pinephone: fix power key behavior during suspend (avoid stuck key during resume)
pinephone keyboard: wait for 100ms after enabling power supply and before probing.

Replace usages of pmb:kconfigcheck-* options with
pmb:kconfigcheck-community which will be required for all devices in
community/main category. This ensures more consistent features &
behavior across devices.
IP5XXX is needed to be able to read PinePhone battery levels. Extra
configs were automatically added by pmbootstrap.
