Add support for both USB controllers and their respective phys on Shikra.

Per request, landed v7 fresh: replaced the old usb_qmpphy node (qcom,shikra-qmp-usb3-phy) and old usb_1 node with v7's versions (qcom,shikra-qmp-usb3-dp-phy, relocated usb_1 block, new usb_2 block), rather than layering v7 on top of the old nodes. Resulting content matches the original patch; no semantic changes beyond superseding the older node definitions.]
On Shikra CQS/CQM platforms, usb-role-switch is handled by PM4125 on primary Type-C port and Cypress PD controller CYPD6129 on second Type-C port. On Shikra IQS platform, usb-role-switch is handled by Cypress PD controller CYPD6129 on both Type-C ports. Since those changes are not yet present, enabling both USB controllers in device mode.

Only the missing &usb_2_hsphy node from this patch was added to those three files; shikra-evk.dtsi had no prior USB wiring and was applied as-is.

…roller Add the device-tree binding documentation for the Cypress cypd6129 and cypd6229 dual Type-C PD controllers. These are used on Shikra CQM/CQS/IQS platforms to handle usb-role-switch for the USB Type-C ports over an I2C interface, similarly to the existing cypd4226 binding. cypd6229 is a variant of cypd6129 and is described with a "cypress,cypd6129" fallback compatible string.

Add cypd6129 and cypd6229 compatible strings to the of_device_id match table so the driver binds to boards describing these Cypress PD controllers in their device tree. No other driver changes are needed since the chip is accessed through the same generic UCSI/HPI I2C register protocol as the existing cypd4226 support.

The version of this patch sent to the list wired CYPD6129 to usb_1_dwc3_hs on CQM/CQS instead, which would have conflicted with that PENDING commit's PM4125 wiring (a DT endpoint can only have one remote-endpoint phandle) and, per updated board-wiring information, does not match the actual hardware: on CQM/CQS, CYPD6129 is wired to the second Type-C port (usb_2) and PM4125 continues to own the primary Type-C port (usb_1), unchanged. This local copy of the patch has been corrected accordingly: the PENDING commit's &pm4125_hs_in/&pm4125_ss_in/usb_1/usb_qmpphy_out wiring on CQM/CQS is restored as-is, and CYPD6129's connector endpoint is wired to the newly added usb_2/usb_2_dwc3_hs instead of usb_1. The PENDING commit's shikra-cqm-som.dtsi portion (&pm4125_typec connector and &pm4125_vbus regulator nodes) is untouched and left in history as-is. shikra-iqs-evk.dts had no such conflict (no PM4125) and is applied as-is. The series needs to be resent upstream with this corrected CQM/CQS wiring.]

On Shikra CQS/CQM platforms, usb-role-switch is handled by PM4125 on
the primary Type-C port and Cypress PD controller CYPD6129 on the
second Type-C port. On Shikra IQS platform, usb-role-switch is
handled by Cypress PD controller CYPD6129 on both Type-C ports.
Add the CYPD6129 typec node under i2c3, wire its connector endpoints
to the corresponding DWC3 controller ports via remote-endpoint
phandles, and switch the associated USB controllers to OTG mode so
role switching can take effect.
