watchdog: pc87413_wdt: Cleanup pc87413 watchdog driver to use
Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87 drivers to use request_muxed_region for accessing the SuperIO area on these chips, and the fact I have a GPIO driver for the pc8741x basically ready for submission, here is a patch to cleanup the pc87413 watchdog driver to use request_muxed_region for accessing the SuperIO area. It also pulls out the details about the SWC IO area on initial driver load, and properly does a request_region for that area - there's no requirement to touch the SuperIO area after doing the initial watchdog enable and IO base retrieval. While I have hardware with a pc87413 on it it is not wired in a way that allows the watchdog to reboot the machine, so I have not been able to fully test these changes - I have checked that the driver correctly initialises itself still and requests the SWC io region ok.
