Convert the usb-connector.txt bindings file to YAML format. This allows
it to be used in dt_bindings_check verification. This patch was
born out of a patch series for the addition of a Type C connector
class port driver[1].

An attempt has been made to maintain the same documentation text and
example structure as was in the .txt file, but wherever needed
modifications have been made to satisfy dt_bindings_check.

Also, update all references to usb-connector.txt to now use
usb-connector.yaml.

The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.

Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.

While converting to the json-schema, let's also take the opportunity to
further specify/clarify some more details about the DT binding.

For example, let's define the label where to put the states nodes, set a

When a DT overlay has a node label that is not present in the live
devicetree symbols table, this error is printed:

  OF: resolver: overlay phandle fixup failed: -22
  create_overlay: Failed to create overlay (err=-22)

which does not help much in finding the node label that caused the problem
and fix the overlay source.

Add an error message with the name of the node label that caused the
error. The new output is:

  OF: resolver: node label 'gpio9' not found in live devicetree symbols table
  OF: resolver: overlay phandle fixup failed: -22
