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.
