mfd: Wolfson Arizona and WM5102 support

This patch series adds the MFD core driver for the WM5102 and other Wolfson Arizona class devices.

The series has a dependency on a new regmap feature, support for wake IRQs. Assuming the code is OK I don't know how you want to handle this
- I've provided a pull request below which in turn pulls in a signed tag from the regmap tree so you can pull into the MFD tree providing you there's no rebases. Alternatively I could carry the code in the regmap tree, though that might get a bit silly as it'll dwarf the actual changes in there.

----------------------------------------------------------------
mfd: Initial support for Wolfson Arizona platform and WM5102 devices

The Wolfson Arizona platform is used to provide common register interface to a series of low power audio hub CODECs, starting with the WM5102. Since the features of these devices work over a range of subsystems an MFD core driver is provided to instantiate the subdevices and arbitrate access between them.

As the new regmap wake IRQ functionality is used as part of the driver it is incorporated as a dependency.
