From: Konrad Dybcio <redacted> 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.
