KVM: ppc: Add DCR access information to struct kvm_run

Device Control Registers are essentially another address space found on PowerPC
4xx processors, analogous to PIO on x86. DCRs are always 32 bits, and can be
identified by a 32-bit number. We forward most DCR accesses to userspace for
emulation (with the exception of CPR0 registers, which can be read directly
for simplicity in timebase frequency determination).
