Federico 'Morg' Pareschi 8839e1c368 devices: virtio: Use mmap for vvu doorbell
This change enables memory mapping of the vfio device doorbell regions so
we can access the vfio bar more efficiently by limiting the scope of the vvu
device interactions with the guest kernel.

BUG=b:231938067
TEST=built and run, verified vvu communication happens as expected
