9abd768a8d mfd: Use mfd cell platform_data for rdc321x 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.

46673ed2cd rdc321x-southbridge: Use mfd_data instead of driver_data
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().

fa6469cb5b gpio: Fix null pointer dereference while accessing rdc321x platform_data
rdc321x-gpio currently fetches its driver specific data by using the
platform_device->platform_data pointer, this is wrong because the mfd
device which registers our platform_device has been added using
mfd_add_device() which sets the platform_device->driver_data pointer
instead.

8deca39e5c mfd: Change rdc321x resources flags to IORESOURCE_IO
The rdc321x southbridge PCI device has no MEM PCI resources that we could
pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the
mem_base argument that we set to NULL. Changing the resources passed to
our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use
those resources as offsets to the PCI configuration space base address of
the southbridge device this is also more adequate.

Implicit slab.h inclusion via percpu.h is about to go away.  Make sure
gfp.h or slab.h is included as necessary.
