vfio: Depend on MMU
commit b2b12db53507bc97d96f6b7cb279e831e5eafb00 upstream.
VFIO_IOMMU_TYPE1 does not compile with !MMU:
../drivers/vfio/vfio_iommu_type1.c: In function 'follow_fault_pfn':
../drivers/vfio/vfio_iommu_type1.c:536:22: error: implicit declaration of function 'pte_write'; did you mean 'vfs_write'? [-Werror=implicit-function-declaration]
So require it.
