Subject: [PATCH v3 0/2] Add Devicetree support for USB controllers on QCS8300

This series aims at enabling USB on QCS8300 which has 2 USB controllers.
The primary controller is SuperSpeed capable and secondary one is
High Speed only capable. Both the High Speed Phys are Femto phys and the
SuperSpeed Phy is a QMP Uni Phy.

Base DT Support has been added for both controllers while only one has
been enabled on Ride Platform. The primary controller has been configured
in device mode. The secondary controller will be enabled in host mode post
addition of SPMI Node which allows control over PMIC Gpios for providing
vbus to connected peripherals.

This series depends on the following series ACKed by upstream maintainers:
Base DT: https://lore.kernel.org/all/20240925-qcs8300_initial_dtsi-v2-0-494c40fa2a42@quicinc.com/

v3 has only been compile tested since only cosmetic changes have been done.

Changes in v3:
Updated commit text for patch-2.
Added dwc3 controller quirks that are applicable.
Fixed nits pointed out in v2.

Changes in v2:
Added quirk to use pipe clk as utmi clk for second controller.
Added wakeup source for second controller.
Modified commit text for DTS change.
