drm/xe/mmio: Add check for minimal BAR size

We initialized the root tile's xe_mmio structure with a new size
of 4MiB without sanity checks to see if mapped GTTMMADR_BAR was
actually at least that size. Check BAR size against first 16MiB,
which is expected minimum BAR size for the one-tile platforms.
