[WATCHDOG] w83977f-watchdog-driver.patch

In a project for my company I've needed to use the watchdog device in a PCM-5335 SBC from AAEON. The watchdog timer is from a Winbond's SuperIO chip, the W83977F. I've made this driver based on two others already on the kernel tree, the w83877f_wdt and the wdt977.
