mfd: remove unused rdc321x southbridge support

This commit removes the rdc321x southbridge support (MFD, GPIO, and Watchdog),
as the older i486 chips can no longer boot Linux.

> Remove this driver, as there is no way to run Linux any more on the
> older chips after i486 support has been removed.

[Severity: Low]
Since the entire platform and driver support is being removed, should we
also clean up the remaining dead references to the RDC321x platform?

Specifically, the reboot fixup code in arch/x86/kernel/reboot_fixups_32.c
has a rdc321x_reset() function and an associated entry in fixups_table that
appear to be left behind now that the hardware is no longer supported.

Additionally, the PCI_DEVICE_ID_RDC_R6030 definition in include/linux/pci_ids.h
is no longer used by any active driver.

Finally, there is a stale "RDC R-321X SoC" entry in MAINTAINERS that might
need to be removed to complete the cleanup.
