regulator updates in 3.6

Linux 3.6, which was released earlier today, saw continuing improvements in the factoring out of common code in the API – lots of new features making drivers smaller and easier to write!

• Initial framework support for GPIO controlled enable signals, saving a bunch of code in drivers.
• Move fixed regulator enable time and voltage mapping table specifications to data.
• Used some of the recent framework enhancements to make voltage change notifications more useful, passing the voltage in as an argument to the notification.
• New drivers for Maxim MAX77686, TI LP872x and LP8788, Samsung S2MPS11, Wolfson Arizona microphone supplies and LDOs
