dt-bindings: phy: qcs615-qmp-usb3dp: Add support for Shikra SoC

Declare the USB-C QMP PHY present on the Qualcomm Shikra SoC. Shikra uses
3 resets to be programmed before initialising the phy. As per the hardware
documentation, the third reset is PHY_PRIM_SP0_BCR, hence naming it "phy".

Also, add remote endpoints and orientation switch support for getting
Type-C orientation information.
