This patch adds a sysfs file with the ab8500 switch off status.
The switch off status contains information of what caused the ab8500
chip to power off. A print during boot is also added.

This patch makes the ab8500 mixed signal chip expose the same
interface for register access as the ab3100, ab3550 and ab5500 chip.
The ab8500_read() and ab8500_write() is removed and replaced with
abx500_get_register_interruptible() and
abx500_set_register_interruptible().

Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500.  The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:

 - Split of the driver into -core and -spi portions, to allow another
   interface layer to be added

 - Addition of interrupt support

 - Switch to MFD core API for handling subdevices

 - Simplification of the APIs to remove a redundant block parameter

 - Rename of the APIs and macros from ab4500_* to ab8500_*

 - Rename of the files from ab4500* to ab8500*

 - Change of the driver name from ab4500 to ab8500
