Add RISC-V implementation of the Coherent Manager Global Control
Register (CMGCR) device. It is based on the existing MIPS CMGCR
implementation but adapted for RISC-V systems.
The CMGCR device provides global system control for multi-core
configurations in RISC-V systems.
This is needed for the MIPS BOSTON AIA board.

I remember asking that already but maybe it was a different
series... Why don't you want this automatically selected by
default? All our codebase does it, why change suddenly?
