Allwinner H6 has a r_watchdog similar to A64.

Declare it in the device-tree.

Just want to point out that i have used the same bindings for WDT and R_WDT.
I think it would be better to also introduce a bindings like
"allwinner,sun50i-h6-r-wdt", "allwinner,sun6i-a31-wdt";

We don't have access to the datasheet of this IP but we can strongly
suppose that wdt and r-wdt are the same.

What do you think?

Regards,
Clement
