iommu/amd: Consolidate PPR log enablement

Browse source

Move PPR log interrupt bit setting to iommu_enable_ppr_log(). Also
rearrange iommu_enable_ppr_log() such that PPREn bit is enabled
before enabling PPRLog and PPRInt bits. So that when PPRLog bit is
set it will clear the PPRLogOverflow bit and sets the PPRLogRun bit
in the IOMMU Status Register [MMIO Offset 2020h].
