Tomáš Kelemen 198dd04be7 RPi-Composite: initial commit (#2037) 
this brings images suited to work OOB for RPi3/4/5 with CRT TV sets. it
comes with preconfigured shaders, core options, readable font, ...
see https://www.lakka.tv/articles/2024/05/02/rpi-composite/

- add new RPiX-Composite devices under RPi project
- RPi3/4-Composite use own kernel config
- RPi5-Composite uses kernel config of RPi5
- remove linux.arm.conf broken symlinks from some devices
- move VULKAN enable to device options
- add splash screens for 480/576 height
- glibc: match kernel version for RPi3/4 (using 5.10.y with "fake" 240p
  patch)
- adjust DEVICE conditions to only match first 4 characters / first 4
  characters + wildcard (various places)
- add specific assets, configs, shaders in retroarch package
- retroarch: adjust default configuration
- linux: add 5.10.y kernel (used by RPi3/4-Composite, see above)
- linux: add patches for 5.10.y kernel
- mkimage: add additional information into cmdline.txt and
  retroarch-overrides.txt
- firstboot.sh: add output (logged in fs-resize.log)
- firstboot.sh: prepend processed overrides with hash
- firstboot.sh: copy core configurations to storage partition
- firstboot.sh: rework wifi autoconfig script
- retroarch: add full default config file and apply changes in the
  package file directly to the config for individual systems (solves
  some issues with core/game overrides when there is no value in the
  config and user creates overrides in first run of retroarch, then
  these overrides are also stored in default config)

commit 5a596921a4636e62843a59b7eab7b87b70a6d296

HID: add ouya HID driver
This driver is a simple implementation to get the controller working and mapped properly.
This driver does not include functionality for the touchpad (yet). The original driver
was taken from from the ouya linux tree and has been simplified. It seems there may have
been other versions of the controller present that had a broken report descriptor. I have
removed that for now.
