Subject: [PATCH 24/29] tmio-fb: use mfd_data instead of driver_data

Use mfd_data for passing information from mfd drivers to mfd
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().  This changes tmio-fb only; mfd drivers with
other cells are not modified.
