ARM: OMAP2: Clean-up mux code
Misc clean-up for the mux code and remove some unnecessary ifdefs. Patch changes debug function so it can be used on both 24xx and 34xx. Changes are mostly for omap2, but patch also cleans up some omap1 and common mux code. Signed-off-by: Tony Lindgren <tony@atomide.com>
