ab8500: Add devicetree support for fuelgauge

Browse Source 
- This patch adds device tree support for fuelgauge driver
- optimize bm devices platform_data usage and of_probe(...)
  Note: of_probe() routine for battery managed devices is made
  common across all bm drivers.
- test status:
  - interrupt numbers assigned differs between legacy and FDT mode.
