vfio/pci: zap_vma_ptes() needs MMU
[ Upstream commit 2a55ca37350171d9b43d561528f23d4130097255 ]
zap_vma_ptes() is only available when CONFIG_MMU is set/enabled.
Without CONFIG_MMU, vfio_pci.o has build errors, so make
VFIO_PCI depend on MMU.
riscv64-linux-ld: drivers/vfio/pci/vfio_pci.o: in function `vfio_pci_mmap_open':
vfio_pci.c:(.text+0x1ec): undefined reference to `zap_vma_ptes'
riscv64-linux-ld: drivers/vfio/pci/vfio_pci.o: in function `.L0 ':
vfio_pci.c:(.text+0x165c): undefined reference to `zap_vma_ptes'
Fixes: 11c4cd07ba11 ("vfio-pci: Fault mmaps to enable vma tracking")
