PATCH 1/1 ARM: dts: Add am335x-pocketbeagle

PocketBeagle Blue is an ultra-tiny-yet-complete open-source USB-key-fob computer.

This board can be indentified by the BPxx value after A335BNLT (BBB) in the at24 eeprom:
BPxx [aa 55 33 ee 41 33 33 35 42 4e 4c 54 42 50 30 30 |.U3.A335BNLTBP00|]

PocketBeagle Blue is an ultra-tiny-yet-complete open-source USB-key-fob computer.

This board can be indentified by the BPxx value after A335BNLT (BBB) in the at24 eeprom:
BPxx [aa 55 33 ee 41 33 33 35 42 4e 4c 54 42 50 30 30 |.U3.A335BNLTBP00|]

Build the dtb with "W=12" and fix all the warnings (unless you've inherited them from the includes).

It looks like i need to clean a few more am335x-* targets, as i used pinmux_X_pins quite a bit...
