Power: DA9052 Battery module V6

Driver for DA9052 battery charger. This driver depends on DA9052 MFD core dirver for definitions and methods.

This patch is functionally tested on Samsung SMDKV6410.

---
As per the thread https://lkml.org/lkml/2011/11/9/42 a transceiver notifications will be added in the usb gadget driver to support setting of USB charge current limit in the battery driver. This patch adds logic to support that notification. Later when usb gadget driver gets modified this driver needs modification only for registration with event notification.

Same on other places.

I fixed this and applied the patch.

Thanks!

I presume this depends on other patches, so I'm fine if this goes via non-battery tree,

If you want me to merge it into battery git tree, I can do it as well.

Thanks!

There should be no direct dependencies for new MFDs - the Kconfig required to depend on the MFD core means that the drivers can't be selected until the core appears.
