OMAP4: PandaBoard: remove unused power regulators
the pandaboard does not use the VUSIM or VAUX1 power regulators on the TWL6030 and are left floating. if the VUSIM and VAUX1 power regulators are initilized, noise on the unloaded regulators generates an overcurrent interrupt causing the system to power down. this patch removes the initialization of the unused power regulators of VUSIM and VAUX1.
