[PATCH 1/2] dt-bindings: dma: ti: k3-bcdma: Add TX channel for AM62A CSIRX BCDMA

[Vaishnav Achath]

J722S CSIRX BCDMA is based on AM62A BCDMA and supports CSI TX channels
in addition to currently supported RX channels. Add TX channel
properties as optional properties in the list so that the same
compatible can be reused. K3 UDMA makes use of TCHAN_CNT
capabilities register to identify whether platform supports
TX channels.
