Andriy Gapon 5022f21bd9 amdsbwd: new driver for AMD SB600/SB7xx watchdog timer
The hardware is compliant with WDRT specification, so I originally
considered including generic WDRT watchdog support, but decided
against it, because I couldn't find anyone to the code for me.
WDRT seems to be not very popular.
Besides, generic WDRT porbably requires a slightly different driver
approach.
