drm/xe: Make xe_mmio_tile_vram_size() static

During xe_mmio_probe_vram(), we already store the values returned from
xe_mmio_tile_vram_size() into the xe_tile structures.
There is no need to call xe_mmio_tile_vram_size() again later during
setup of the STOLEN region. Just use the values stored in the root tile.
