Implement RESET_BASE register which is local to each VP and a write to
it changes VP's reset exception base. Also, add OTHER register to
allow a software running on one VP to access other VP's local registers.
Guest can use this mechanism to specify custom address from which a VP
will start execution.

Create Cluster Power Controller and add a link to the CPC MemoryRegion
in GCR. Guest can enable / map CPC to any physical address by writing to
the memory-mapped GCR_CPC_BASE register.
Set vp-start-reset property to 1 to allow only first VP to run from reset.
Others are brought up by the guest via CPC memory-mapped registers.
