The 'type' field used in the driver to discern SoC differences is confusing
so change it to the more apt 'model'. We considered using 'family' but
this conflicts with Broadcom's conception of a family; for example, 7216a0
and 7216b0 chips are both considered separate families as each has multiple
derivative product chips based on the original design.
