OMAP4 clock: drop the CLOCK_IN_OMAP4430 clock flag

The CLOCK_IN_OMAP4430 clock flag is not currently needed in the OMAP4
ES1 clock tree, and platform discrimination via clock flags is
deprecated in favor of the clkdev mechanism, so, drop it.  (The OMAP4
clock tree autogeneration script has been updated accordingly.)
