* Factor out chipset family detection from init_chipset_sis5513()
to sis_find_family().
* Use sis_find_family() in sis5513_init_one() to fail early if the
chipset is unsupported.
* Keep a local copy sis5513_chipset in sis5513_init_one()
and set .udma_mask according to chipset family.
* Remove no longer need ->ultra_mask setting from init_hwif_sis5513().
