Subject: [PATCH v4 4/6] dt-bindings: clock: mediatek: update audsys documentation to adapt MFD device

The MediaTek audio hardware block that exposes functionalities that are
handled by separate subsystems in the kernel. These functions are all
mapped somewhere at 0x112xxxxx, and there are some control bits are mixed
up with other functions within the same registers.

This patch modifies example to illustrate child nodes.
