[PATCH v3 0/7] FriendlyELEC NanoPC-T6 improvements

[Marcin Juszkiewicz]

This series updates FriendlyELEC NanoPC-T6 situation. There is non-LTS
(2301) version of a board and LTS (2310) version.

This series creates separate DTS for NanoPC-T6 LTS (on top of non-LTS
one) and enables USB 2.0 ports on it.

Then set of changes for both versions are done:

- enable USB-C port (one orientation only)
- enable Mali GPU
- enable IR receiver (not tested)
- enable SPI flash (present on LTS, optional on non-LTS)
