2.25.1
Add support for compatible sama7g5-wdt.
The sama7g5 wdt is the same hardware block as on sam9x60.
Adapt the driver to use the sam9x60/sama7g5 variant if either
of the two compatibles are selected (sam9x60-wdt/sama7g5-wdt).

I applied the series to my watchdog-next branch. That is all I can do

Please ignore this comment which has no meaning as all the content of
this series must progress with the "watchdog" tree and not at91->arm-soc!
Sorry for the noise and confusion. I'm removing the patches from at91-dt
right now.
