[PATCH 5.6 178/194] arm64: dts: imx8mn: Change SDMA1 ahb clock for imx8mn

From: Adam Ford <aford173@gmail.com>

commit 15ddc3e17aec0de4c69d595b873e184432b9791d 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: 6c3debcbae47 ("arm64: dts: freescale: Add i.MX8MN dtsi support")
