KVM: PPC: Book3S HV: Handle guest using doorbells for IPIs
* SRR1 wake reason field for system reset interrupt on wakeup from nap
is now a 4-bit field on P8, compared to 3 bits on P7.
* Set PECEDP in LPCR when napping because of H_CEDE so guest doorbells
will wake us up.
* Waking up from nap because of a guest doorbell interrupt is not a
reason to exit the guest.
