Subject: [PATCH 1/2] arm64: dts: imx93: assign the correct ipg/ahb clock for usdhc

From: Haibo Chen <haibo.chen@....com>

Assign the correct ipg/ahb clock for usdhc according to CCM.
Also config IMX93_CLK_USDHC1 to 400MHz to support eMMC HS400ES mode.

Fixes: ec8b5b5058ea ("arm64: dts: freescale: Add i.MX93 dtsi support")
