v12 cover Enable IPQ9754 USB

This patch series adds the relevant phy and controller configurations for enabling USB on IPQ9754

Portions of the patchset have been merged. Please see
https://lore.kernel.org/lkml/ZGN9gchu7dRb6QwC@matsya/

[v11]:
- Rename dwc_0 -> usb_0_dwc3
- Minor change in qcom,sc8280xp-qmp-usb3-uni-phy.yaml to factor in latest updates to the file

[v10]:
- Fix regulator definitions
- Address couple of other comments

[v9]:
- Update bindings to make power-domains as optional since IPQ9574 doesn't have GDSCs

[v8]:
- Update bindings for the clock name change
[v7]:
- com_aux -> cfg_ahb in patch 7

[v6]:
- Incorporated review comments
- Resolve make dtbs_check messages
- Fixed pcs_usb offset

- Move qmp phy DT node to newer specification

[v4]:
- Incorporated review comments
- Address all 'make dtbs_check' errors

[v3]:
- Incorporated review comments regarding coding style

[v2]:
- Incorporated review comments regarding coding style, maintaining sorted order of entries and unused phy register offsets
- Removed NOC clock entries from DT node (will be implemented later with interconnect support)
- Fixed 'make dtbs_check' errors/warnings

[v1]:

- Resolved all 'make dtbs_check' messages

Changes in v5:
- Fix additional comments
- Edit nodes to match with qcom,sc8280xp-qmp-usb3-uni-phy.yaml
- 'make dtbs_check' giving the following messages since ipq9574 doesn't have power domains. Hope this is ok

Changes in v4:
- Use newer bindings without subnodes
- Fix coding style issues

Changes in v3:
- Insert the nodes at proper location

Changes in v2:
- Fixed issues flagged by Krzysztof
- Fix issues reported by make dtbs_check
- Remove NOC related clocks (to be added with proper interconnect support)

These regulators are provided by the board, not by the SoC itself. As such they should go to the board DT files. Please excuse me for not noticing this during earlier review stage. I was too concentrated on not making them non-USB-specific.

Will move it to board dts.

Thanks

Add USB phy and controller related nodes

SS PHY need two supplies and HS PHY needs three supplies. 0.925V and 3.3V are from fixed regulators and 1.8V is generated from PMIC's LDO
