regmap: Updates for 3.5

A surprisingly large series of updates for regmap this time, mostly due
to all the work Stephen Warren has done to add support for MMIO buses.
This wasn't really the target for the framework but it turns out that
there's a reasonable number of cases where it's very helpful to use the
register cache support to allow the register map to remain available
while the device is suspended.

- A MMIO bus implementation, contributed by Stephen Warren. Currently this
  is limited to 32 bit systems and native endian registers.
- Support for naming register maps, mainly intended for MMIO devices with
  multiple register banks. This was also contributed by Stephen Warren.
- Support for register striding, again contributed by Stephen Warren and
  mainly intended for use with MMIO as typically the registers will be a
  fixed size but byte addressed.
- irqdomain support for the generic regmap irq_chip, including support
  for dynamically allocate interrupt numbers.
- A function dev_get_regmap() which allows frameworks using regmap to
  obtain the regmap for a device from the struct device, making life a
  little simpler for them.
- Updates to regmap-irq to support more chips (contributed by Graeme
  Gregory) and to use irqdomains.
- Support for devices with 24 bit register addresses.

The striding support collided with all the topic branches so the
branches look a bit messy and eventually I just gave up.  There's also
the TI Palmas driver and a couple of other isolated MFD patches that
all depend on new regmap features so are being merged here.
