Subject: [PATCH] arm64: dts: ti: k3-j784s4-main: Correct McASP DMAs

From: Parth Pancholi <parth.pancholi@...adex.com>

Correct the McASP nodes - mcasp3 and mcasp4 with the right
DMAs thread IDs as per TISCI documentation [1] for J784s4.
This fixes the related McASPs probe failure due to incorrect
DMA IDs.

Fixes: 5095ec4aa1ea ("arm64: dts: ti: k3-j784s4-main: Add McASP nodes")
