Cleanups, More LibreELEC Stuff, more permission fixes, Misc switch stuff. (#1930)
* libCEC: Update to 6.0.2

* L4T: Switch-bsp: Fix typos

* Switch: Fix all permission issues with running kodi as a non-root user.

* L4T: Switch: Minor code cleanups

* Add upower and libgudev so kodi can get battery stats

Upower was removed from libreELEC in 2013 with this commit: 3a130cd5009c8d3595b8afcde2421324572ce58b
This was a stupid choice as it is the only option in kodi for supplying any battery statitistics. Currently broken.
This patchset: https://github.com/xbmc/xbmc/pull/17327/commits for kodi seemingliy wants to fix the issue(Doesnt, is more of a new way to deal with dbus in general), but will still require that upower be available for battery.

* Switch: LibreELEC: Peripheral.Joystick: Fix Add Patches from PR's upstream to fix issues with udev devices

* Switch: LibreElec: Peripheral.Joystick: Add Nintendo Switch udev joystick mappings

* Switch: LibreELEC: Peripheral.Joystick: Force Udev controller driver as default.
