Subject: [PATCH 5.8 162/177] arm64: dts: imx8mp: correct sdma1 clk setting

From: Robin Gong <yibin.gong@....com>

commit 66138621f2473e29625dfa6bb229872203b71b90 upstream.

Correct sdma1 ahb clk, otherwise wrong 1:1 clk ratio will be chosed so
that sdma1 function broken. sdma1 should use 1:2 clk, while sdma2/3 use
1:1.
