dt-bindings: watchdog: dw-wdt: Support devices with asynch clocks
DW Watchdog IP core can be synthesised with asynchronous timer/APB
clocks support (WDT_ASYNC_CLK_MODE_ENABLE == 1). In this case
separate clock signals are supposed to be used to feed watchdog timer
and APB interface of the device. Let's update the DW Watchdog DT node
schema so it would support the optional APB3 bus clock specified along
with the mandatory watchdog timer reference clock.
