aw_sid(4): Add support for Allwinner H3

Description

aw_sid(4): Add support for Allwinner H3

The sid controller on the H3 is generally identical in location, size, and
efuse offset to the a64 and the a83t. The main difference is that the H3 has
a silicon bug that sometimes causes the rootkey (at least) to be garbled
unless first read by the prctl registers.

This device is currently not in our DTS and, as of now, is not yet present
in mainline Linux DTS.

Tested on: OrangePi One
