+Optional properties for AST2500- and AST2600-compatible watchdogs:
+ - aspeed,reset-mask: A bitmask indicating which peripherals will be reset if
+ the watchdog timer expires. On AST2500 this should be a
+ single word defined using the AST2500_WDT_RESET_* macros;
+ on AST2600 this should be a two-word array with the first
