Subject: [RFC PATCH v3 0/6] Add A1 Soc audio clock controller driver

This series adds support for audio clock and reset controllers on A1 SoC family.

Changes v2 -> v3
 - reset:
   * added auxiliary device
 - yaml:
   * added declaration of optional clocks
   * fixed names in example and another cosmetics
 - clocks:
   * reworked naming
   * stop using of "core" clock name
   * fixed wrong parenting

Changes v1 -> v2:
 - Detached from v1's series (patch 2, 3, 4, 25).
 - Reuse some of defines from axg-audio;
 - Split the controller into two memory regions.
