Add a region_size field to struct vfio_pci_driver_ops so drivers can declare how much DMA-mapped region they need. The mlx5 driver will need ~18MB for firmware pages. Existing drivers pass in the sizeof their state struct. Since drivers all use only their declared state we can use the value directly and remove the SZ_2M hard coding.
