This modifies the TI Davinci PLL clock driver to allow for the case
when dev == NULL. On some (most) SoCs that use this driver, the PLL
clock needs to be registered during early boot because it is used
for clocksource/clkevent and there will be no platform device available.

PLL2 SYSCLK1 on DM646x is connected to DDR2 PHY and cannot
be disabled. Mark it so to prevent unused clock disable
infrastructure from disabling it.
