Intel MID platform battery driver.

Ok this should fix the core problems. I've not switched to threaded IRQs although I've marked that down for future attention when there is a bit more time.

The PMIC Battery driver provides battery charging and battery gauge functionality on Intel MID platforms. This provides the basic functions. There are some USB drivers to merge before the selection of charging between the different USB power levels can be enabled.

Moved to a platform device by Alek Du.

Some cleanups by Alan Cox.
