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: https://gist.github.com/pietrushnic/787cbf63f610ff4f6b4ac13e5c20b872 SeaBIOS from PC Engines repository (https://github.com/pcengines/seabios) works fine. Those changes are planned for upstream.
