plat/marvell/a8k: add Globalscale Mochabin support

Add support for Globalscale MOCHAbin board.

Its based on Armada 7040 SoC and ships in multiple DRAM options:
* 2GB DDR4 (1CS)
* 4GB DDR4 (1CS)
* 8GB DDR4 (2CS)

Since it ships in multiple DRAM configurations, an
Armada 3k style DDR_TOPOLOGY variable is added.
Currently, this only has effect on the MOCHAbin, but
I expect more boards with multiple DRAM sizes to be
supported.
