Shikra USB3 QMP PHY uses a single-PHY DT binding (#phy-cells = <0>), which is not supported by the existing QMP combo PHY driver. Add a dedicated USB3-only QMP PHY driver for Shikra, porting the PHY initialization sequence and configuration tables from Linux(7.2v) drivers/phy/qualcomm/phy-qcom-qmp-usbc.c. The driver is selected through PHY_QCOM_QMP_USB3_LEGACY and enables USB3 PHY bring-up on Shikra platforms. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Enable the QMP USB3 PHY driver in the Qualcomm common defconfig. This allows USB3 PHY initialization support when the corresponding platform DT is enabled. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Enable the USB QMP PHY node in the U-Boot device trees for the Shikra IQS EVK platform. This allows the QMP USB3 PHY driver to probe and initialize the USB3 PHY during boot. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>

This PR enables USB3 PHY support on the Qualcomm Shikra platform by integrating the newly added QMP USB3 PHY driver and updating the platform configuration and device tree accordingly.
