Add counters to track number of times we switch from guest real mode to host virtual mode during an interrupt-related hyper call because the hypercall requires actions that cannot be completed in real mode. This will help when making optimizations that reduce guest-host transitions. It is safe to use an ordinary increment rather than an atomic operation because there is one ICP per virtual CPU and kvmppc_xics_rm_complete() only works on the ICP for the current VCPU. The counters are displayed as part of IPC and ICP state provided by /sys/debug/kernel/powerpc/kvm* for each VM.
