MIPS: KVM: Clean up register definitions a little

Browse Source 
Clean up KVM_GET_ONE_REG / KVM_SET_ONE_REG register definitions for
MIPS, to prepare for adding a new group for FPU & MSA vector registers.

Definitions are added for common bits in each group of registers, e.g.
KVM_REG_MIPS_CP0 = KVM_REG_MIPS | 0x10000, for the coprocessor 0
registers.
