dt-bindings: usb: qcom,dwc3: fix clock matching
The bindings defined strict clocks but several variants do not use them in such order. Split the clocks and clock-names per variants to match current DTS usage. In few cases this might not be complete match, due to incomplete DTS.

Several clocks are used, depending on the variant. Typical ones are::
|
||||
- cfg_noc:: System Config NOC clock.
|
||||
- core:: Master/Core clock, has to be >= 125 MHz for SS operation and >=
|
||||
60MHz for HS operation.

- iface:: System bus AXI clock.

- sleep:: Sleep clock, used for wakeup when USB3 core goes into low

|

- mock_utmi:: Mock utmi clock needed for ITP/SOF generation in host
|

mode. Its frequency should be 19.2MHz.
