watchdog: Convert rdc321x_wdt to use southbridge pci device
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.
