KVM: PPC: Book3S HV: Move interrupt delivery on guest entry to C code
This is based on a patch by Suraj Jitindar Singh.
This moves the code in book3s_hv_rmhandlers.S that generates an
external, decrementer or privileged doorbell interrupt just before
entering the guest to C code in book3s_hv_builtin.c. This is to
make future maintenance and modification easier. The algorithm
expressed in the C code is almost identical to the previous
algorithm.
