[PATCH 20/29] wm8400-codec: use mfd_data instead of driver_data (v2)

[Andres Salomon <dilinger@queued.net>]

Use mfd_data for passing information from mfd drivers to soc
clients.  The mfd_cell's driver_data field is being phased out.

Clients that were using driver_data now access .mfd_data
via mfd_get_data().

v2: add some missing mfd/core.h includes.
