    xen/arm: Fix HAS_PASSTHROUGH selection
    
    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.
    
    Fixes: 163c6b589879 ("xen/arm: pci: introduce PCI_PASSTHROUGH Kconfig 
option")
