dt-bindings: arm: hisilicon: convert Hi6220 domain controller bindings to json-schema
Convert the Hisilicon Hi6220 domain controllers binding to DT schema
format using json-schema. All of them are grouped into one yaml file, to
help users understand differences and avoid repeated descriptions.

Hisilicon designs some special domain controllers for mobile platform,
14
+
such as: the power Always On domain controller, the Media domain
15
+
controller(e.g. codec, G3D ...) and the Power Management domain
16
+
controller.
17
+
18
+
The compatible names of each domain controller are as follows:
19
+
Power Always ON domain controller --> hisilicon,hi6220-aoctrl
20
+
Media domain controller --> hisilicon,hi6220-mediactrl
21
+
Power Management domain controller --> hisilicon,hi6220-pmctrl
