can rely on the efuse_sma register to tell us the maximum speed. In the

are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we

need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.
