Subject: [PATCH 3/3] dt-bindings: clock: amlogic,gxbb-aoclkc: Update bindings

On the first revision of the bindings, only the gates + resets were known
in the AO Clock HW, but more registers used to configures AO clock are known
to be spread among the AO register space.
This patch adds these registers to the Ao Clock bindings with direct access
and shared extcon access.
