arm: mvebu: Add Marvell's integrated CPUs

Marvell's switch chips with integrated CPUs (collectively referred to as
MSYS) share common ancestry with the Armada SoCs. Some of the IP blocks
(e.g. xor) are located at different addresses and DFX server exists as a
separate target on the MBUS (on Armada-38x it's just part of the core
complex registers).
