aw_sid: Add support for a64

Browse Source 
Newer Allwinner SoCs have nearly identical SID controllers with efuse space
starting at 0x200 into their register space and thermal data available at
0x234, making all of these fairly trivial additions.

The h3 will be added at a later time after some testing, due to a silicon
bug that causes the rootkey (at least) to be read incorrectly unless first
read via the control register.
