[PATCH v1 12/19] mfd: Use mfd cell platform_data for wm8400 cells platform bits

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

v0 -> v1: Use dev_get_platdata instead of directly accessing the platform_data
pointer.
