mfd: Unify abx500 headers in mfd/abx500
This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

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
