plat: marvell: octeontx: add support for t9130

CN-9130 has single CP0 inside the package and 2 additional one from MoChi
interface. In case of db-9130-modular board the MCI interface is routed to:
- on-board CP115 (MCI0)
- extension board CP115 (MCI1)

The board is based on DIMM DDR.

The 9130 has up to 3CP, and decoding windows looks like below:
