OMAP3: Setup MUX settings for SDRC CKE signals
This patches ensures the MUX settings are correct for the SDRC CKE signals to SDRAM. This allows the self-refresh to work when 2 chip-selects are in use. A warning is thrown away in case the initial muxing is incorrect, in order to track faulty or old-dated bootloaders. Note: The CONFIG_OMAP_MUX and CONFIG_OMAP_MUX_WARNINGS options must be enabled for the mux code to have effect.
