OMAP2+ clock: clean up clkt_clksel.c
This patch cleans up arch/arm/mach-omap2/clkt_clksel.c. It: - makes several functions static that are not called outside the file; - adds documentation; - makes some code paths easier to read (hopefully), by breaking up compound statements and removing redundant checks; - converts some pr_err()s that indicate clock tree data problems into WARN()s, so they are more likely to be noticed; - and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper home, since it is not clksel-specific.
