pnv/psi: Initialize the PSIHB interrupts to match hardware 

On the powernv9 and powernv10 machines, the PSIHB interrupts are
currently initialized with a PQ state of 0b01, i.e. interrupts are
disabled. However real hardware initializes them to 0b00 for the
PSIHB. This patch updates it, in case an hypervisor is in the mood of
checking it.
