This RFC follows the discussion about having reset driver in the clock tree
[1]. Ideally those should reside in the reset part of tree.
Also the code of the amlogic reset driver is very similar between the 2 trees
and could use the same driver code.
This RFC moves the reset driver of audio clock controller of the g12 and
sm1 SoC family to the reset tree, using the auxiliary bus.
The infrastructure put in place is meant to be generic enough so we may
eventually also move the reset drivers in the meson8b and aoclk clock
controllers.
