am33xx: pepper: Enable pull-ups for pushbuttons

GPIO54 and GPIO55 are used as user buttons; these pins need to have
pull-ups turned on in order to get a change when the button is pushed.
Note: this change requires CONFIG_OMAP_MUX=y to be effective.

Using Switch 2 (gpmc_a6.gpio1_22 / gpio54) as the power and Switch 3 (gpmc_a7.gpio1_23 / gpio55) as the menu button.
