OMAP3: Overo: Clean up pin mux and GPIO configuration
* Make Overo GPIO114 an input for touchscreen PENDOWN
* Make Overo GPIO144-147 readable
* Make Overo EHCI pinmux match beagle rev c setup
* Adjust pinmux for SMSC911X network chip support
* Remove unnecessary GPIO setup
* Fix merge error in Makefile
