[PATCH 2/3] regulators: Update of ab8500 driver

From: Bengt Jonsson
Date: Tue Nov 23 2010 - 13:29:10 EST

This patch updates the driver with some bug fixes, support
for v2 hardware, support for regulator_count_voltages,
changes for reading the board config, added indexing of
the regulator array and added debug prints.
