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*

This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.
This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.
