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).

Guenter, Wim,
How do we proceed? Do I take this "driver" patch through my tree which
goes to arm-soc or do you take it with the watchdog tree?
I'm planning to send my pull-requests before the end of this week.
Best regards,
Nicolas
