ARM: sunxi: Add sun6i/sun8i timer block register definition

The RTC hardware has been moved out of the timer block on sun6i/sun8i.
In addition, there are more watchdogs available.

Also note that the timer block definition is not completely accurate
for sun5i/sun7i. Various blocks are missing or have been moved out.
