Subject: [PATCH v3 1/2] dt-bindings: dma: ti: k3-bcdma: Add J722S CSI BCDMA

J722S CSI BCDMA is similar to J721S2 CSI BCDMA and supports both RX and TX
channels but has a different PSIL thread base ID which is currently
handled in k3-udma driver. Add an entry for J722S CSIRX BCDMA.

Signed-off-by: Vaishnav Achath <vaishnav.a@...com>
---

V2->V3:
  * Added missing compatible entry missed in v2.
  * Address Krzysztof's review comments to not wrap commit
  message too early.

V1->V2:
  * Address review from Conor to add new J722S compatible
  * J722S BCDMA is more similar to J721S2 in terms of RX/TX support,
  add an entry alongside J721S2 instead of modifying AM62A.
