HAS_PASSTHROUGH should only be selected on MMU systems. It's been like
that until commit 163c6b589879 added possibility to select HAS_PASSTHROUGH
if PCI_PASSTHROUGH is enabled on Arm64. This is incorrect as it may result
in enabling passthrough/ build on MPU systems. PCI_PASSTHROUGH should
depend on HAS_PASSTHROUGH instead.
