Changes in v3:
- Added qmp_v7_usb3phy_regs_layout like Dmitry suggested
- Added Krzysztof's R-b tag to 1st patch
- Added Dmitry's R-b tag to 2nd patch
- Link to v2: https://lore.kernel.org/r/20231122-phy-qualcomm-usb3-uniphy-x1e80100-v2-0-1a3e1d98564e@linaro.org

Changes in v2:
- Added qmp_usb_offsets_v7, as Dmitry suggested
- Properly sorted the init tables, cfg struct and compatible entry, as
suggested by Johan
- Add entries to allOf section in the schema, as suggested by Krzysztof
- Link to v1: https://lore.kernel.org/r/20231122-phy-qualcomm-usb3-uniphy-x1e80100-v1-0-3f5bd223d5b4@linaro.org
