[PATCH v2 2/2] dmaengine: ti: k3-udma: Add support for J722S CSI BCDMA

[Vaishnav Achath <vaishnav.a@ti.com>]

J722S CSI BCDMA is similar to J721S2 CSI BCDMA but there are
slight integration differences like different PSIL thread
base ID which is handled in the driver. Add an entry
to support J722S CSIRX.

J722S TRM (11.2 Data Movement Subsystem):

V1->V2:
	* Add new compatible for J722S instead of modifying AM62A

V1: https://lore.kernel.org/all/20241125083914.2934815-2-vaishnav.a@ti.com/

CSI2RX capture test results on J722S EVM with 4 x IMX219:
