This patch-set adds device tree binding for ab8500 battery-managed
devices. Removes the redundant platform structure maintained
across bm devices and implements common DT probe routine across all the
modules.

Test status:
a) Tested across 'legacy platform data' and DT binding support
	a.1) ab8500_charger driver fails to get regulator in the
		legacy platform mode.
b) Interrupt numbers assigned differs between legacy and FDT mode.
    (a) Legacy platform_data Mode:

c) Event handlers across bm-modules have been verified only
   during 'battery discharge process' as 'battery charging process'
   depends on ab8500-usb code
