pcengines/apu2: add board support

Initial work based on db-ft3b-ls and code released by Eltan. Board
    boots with some limitation.

Now the AGESA binary is harcoded and board specific until it's fixed
    by the SoC vendor.

memtest86+ from external repo skips looking for SPD on SMBus, which when
    performed cause memtest86+ to hang. Still didn't tried whole test suit.

SeaBIOS 1.9.3 have some problems with USB which lead to no booting in
    some cases. Full log:

SeaBIOS from PC Engines repository (https://github.com/pcengines/seabios)
    works fine. Those changes are planned for upstream.
