[PATCH 1/5] dt-bindings: phy: qcom,qmp-usb3-dp: Extend X1E description for USB4

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio at oss.qualcomm.com>

Some instances of the QMP combo PHY (called USB43DP) feature a third
functional sub-block, responsible for USB4/Thunderbolt 3 communication.

Compared to the today's state of the binding, one more clock (P2RR2P -
PHY-to-Router, Router-to-PHY) needs to be enabled for the PHY to be
able to switch to USB4 mode. Allow that for X1E.

Also, add a bindings define to let consumers access it.
