[PATCH v4 0/4] Add DT Support for USB on Shikra

[Krishna Kurapati]

Shikra has two USB controllers. Adding both USB controllers support
in device mode in this series.

Changes in v4:
- Enable both controllers in CQS/CQM platform
- Fixed iface clock in usb_2 node
- Skipped adding RB tags obtained from Konrad since on CQM/CQS, second
  controller also is enabled in v4. Also specified dr_mode as peripheral
  for first controller.

Changes in v3:
- USB changes were sent as part of consolidated submission in v2, but
  they were later dropped since bindings had to be updated.
- Remove double vote on USB3_PRIM_CLKREF and also removed xo clock.
- Uses &mpm as interrupt reference (sashiko bot)

Link to v2:
https://lore.kernel.org/all/20260519-shikra-dt-v2-0-c01b90fb4395@xxxxxxxxxxxxxxxx/

Changes in v2:
- Moved to using mpm interrupt handler for ss phy irq (sashiko bot)
