Subject: [PATCH] dmaengine: ti: k3-psil-am62a: Fix SPI PDMA data

AM62Ax has 3 SPI channels where each channel has 4x TX and 4x RX
threads. Also fix the thread numbers to match what the firmware expects
according to the PSI-L device description.

Fixes: aac6db7e243a ("dmaengine: ti: k3-psil-am62a: Add AM62Ax PSIL and PDMA data")

This is the same fix done for a different SoC (AM62) here:
