From: Adam Ford <aford173@xxxxxxxxx>
commit 24a572bf67994223e722cadfe663e15ba221882a upstream.
Using SDMA1 with UART1 is causing a "Timeout waiting for CH0" error.
This patch changes to ahb clock from SDMA1_ROOT to AHB which
fixes the timeout error.
Fixes: a05ea40eb384 ("arm64: dts: imx: Add i.mx8mm dtsi support")
