vfio/fsl-mc: Allow userspace to MMAP fsl-mc device MMIO regions
Allow userspace to mmap device regions for direct access of
fsl-mc devices.
QBman CENA registers are cacheable and non-shareable but map
CENA region (marked as REGION_TYPE_CACHEABLE) to be the non-cacheable
to avoid coherency issues if a user migrates to another core.
