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.

e090d506c3 mfd: Add support for the RDC321x southbridge
This patch adds a new MFD driver for the RDC321x southbridge. This southbridge
is always present in the RDC321x System-on-a-Chip and provides access to some
GPIOs as well as a watchdog. Access to these two functions is done using the
southbridge PCI device configuration space.
