powerpc/powernv: Fix CPU hotplug to handle waking on HVI
commit 9b256714979fad61ae11d90b53cf67dd5e6484eb upstream.
The IPIs come in as HVI not EE, so we need to test the appropriate
SRR1 bits. The encoding is such that it won't have false positives
on P7 and P8 so we can just test it like that. We also need to handle
the icp-opal variant of the flush.
