We should split this patch into two. The A3 support is not yet present
in any u-boot tree, so it would be premature to update any socs to
emulate the A3. We can expect support in the coming months, and when
that lands we can consider updating.

However filling out some of the clock register reset values is
important for guests to calculate sensible clock rates, so we should
do that now for the A1.
