[PATCH 2/3] MFD: AB3100 interface change to ABx500

From: Linus Walleij
Date: Mon Apr 12 2010 - 19:05:52 EST

The interface for AB3100 is changed to make way for the chips
AB3550, AB5500 and future ST-Ericsson analog baseband chips.
The arguments to mask_and_set_register function have changed and a
u8 bank have been added since the new chips have several banks.
