watchdog: Add driver for Intel OC WDT

Browse source

Add a driver for the Intel Over-Clocking Watchdog found in Intel
Platform Controller (PCH) chipsets. This watchdog is controlled
via a simple single-register interface and would otherwise be
standard except for the presence of a LOCK bit that can only be
set once per power cycle, needing extra handling around it.
