powerpc/powernv/pci: Fix m64 checks for SR-IOV and window alignment
Commit 5958d19a143e checks for prefetchable m64 BARs by comparing the
addresses instead of using resource flags. This broke SR-IOV as the m64
check in pnv_pci_ioda_fixup_iov_resources() fails.
The condition in pnv_pci_window_alignment() also changed to checking
only IORESOURCE_MEM_64 instead of both IORESOURCE_MEM_64 and
IORESOURCE_PREFETCH.
Revert these cases to the previous behaviour, adding a new helper function
to do so. This is named pnv_pci_is_m64_flags() to make it clear this
function is only looking at resource flags and should not be relied on for
non-SRIOV resources.
Fixes: 5958d19a143e ("Fix incorrect PE reservation attempt on some 64-bit BARs")
