Yemike Abhilash Chandra 1c067005b0 media: dt-bindings: ti,ds90ub960: Add support for DS90UB954-Q1 
DS90UB954-Q1 is an FPDLink-III deserializer that is mostly register
compatible with DS90UB960-Q1. The main difference is that it supports
half of the RX and TX ports, i.e. 2x FPDLink RX ports and 1x CSI TX
port. Therefore, add support for DS90UB954 within the existing bindings.
