[PATCH 5.4 008/222] arm64: dts: imx8mm: Change SDMA1 ahb clock for imx8mm

[Greg Kroah-Hartman]

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.
