[PATCH v4 0/8] 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 common DTSI for both boards and then separate
NanoPC-T6 and NanoPC-T6 LTS DTS files. This way T6 gets MiniPCIe section
and T6-LTS gets USB20 section.

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)
- enable Mask Rom button as input device
