AW_CLK_FACTOR_HAS_BIT_COND and AW_CLK_FACTOR_POWER_OF_FOUR have been added to
support ahb1 and the cpux PLLs on the a83t. In a83t-land,dd a means to specify mask/value for the prediv condition instead of shift/width/value for clocks that have a more complex mux scenario.
- ahb mux = 0x10 and 0x11 both mean PLL_PERIPH/prediv.
Specifically, - cpux PLLs 'p' factors have /1 and /4 dividersahb1 on the a83t has the prediv applied if mux is either b10 or b11.
