phb4: Avoid MMIO load freeze escalation on every chip
The commit f397cc30bdf8 ("phb4: Only escalate freezes on MMIO load where
necessary") introduced a change to restrict escalation to the chips that
actually need it. However it missed one case which still causes the
escalation on every chip. This affects EEH recovery to cause full
PHB reset on some chips which is not necessary. This patch fixes that.
Also, add a check for p9 chip in phb4_escalation_required() function.
