Kevin Hilman 46232a3622 ARM: OMAP: PM: only register TWL with voltage layer when device is present 
Current code registers voltage layer details for TWL PMIC even when a TWL
has not been registered.  Fix this to only register the TWL with voltage
layer when the TWL PMIC is initialized by board-level code.
