mfd: Add initialisation callback for WM8350
Some functions of the WM8350 require board-specific initialisation on
startup. Provide a callback to the WM8350 driver in platform data
for platforms to use to configure the chip. Use of a callback allows
platforms to control the ordering of initialisation which can be
important.
