ARM: OMAP: Allow registering pin mux function
This patch changes pin multiplexing init to allow registering custom function. The omap_cfg_reg() func will be split into omap processor specific functions in later patch. This is done to make adding omap3 pin multiplexing easier. Signed-off-by: Tony Lindgren <tony@atomide.com>
