-The RDC321x MFD southbridge driver will pass a reference to the southbridge
-PCI device which should be used by the watchdog driver for its operations.
-This patch converts the watchdog driver to use the pci_dev pointer and make use
-of the base register resource which is passed along with the platform device.

-Changes from v2:
-- replaced rdc321x_pci_{read,write}
-- use the pci_dev pointer passed as platform_data
