clk: davinci: pll: allow dev == NULL 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.

clk: davinci: psc: allow for dev == NULL On some davinci SoCs, we need to register the PSC clocks during early boot because they are needed for clocksource/clockevent. These changes allow for dev == NULL because in this case, we won't have a platform device for the clocks.
