Update Qualcomm PMIC Type-C examples to follow the USB-C connector
schema. The USB-C connector should have three ports (USB HS @0,
SSTX/RX @1 and SBU @2 lanes). Reorder ports accordingly and add SBU port
connected to the SBU mux (e.g. FSA4480).

Update examples to follow usb-c-connector schema wrt. ports definitions.
---
Changes in v2:
- Dropped patch removing the role-switching port. We do not use it, but
  it can become useful by other designs.
- Link to v1: https://lore.kernel.org/r/20240322-typec-fix-example-v1-0-6b01c347419e@linaro.org
