ARM: OMAP3: clock: use clk_features flags for omap3 DPLL4 checks
DPLL4 can't be reprogrammed on OMAP3430 ES1.0 due to hardware limitation. Currently, the code does runtime omap_rev() check to see the chip it is being executed on, instead, change this to use clk_features flags. This avoids need for runtime omap_rev() checks.
