ARM: dts: msm: add DT file for APQ8084 MTPs with SMB1359

There exists a new APQ8084 MTP board variant with the SMB1359 charger
instead of SMB1357. Create a new top level devicetree file to support
the new board.

The board id for this new board variant will be <8 1> (platform-id = 8 and
subtype-id = 4).
