mfd: New AB8500 driver
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
