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.

Please report an error for invalid num_vps values (0 or >MAX).
Per the next patch:
#define VPS_MAX 64
Is it possible to have a config with 7, 24 or 35 vps?
64 is maximum, and we can have fewer than 64 vps.
So, yes, it is possible to have that configuration.
Please provide a test with 7 and 35 VPs then.
Thanks!
