Re: [PATCH 1/7] arm64: dts: imx8mm-venice-gw700x: Increase HS400 USDHC clock speed

The IMX8M reference manuals indicate in the USDHC Clock generator section that the clock rate for DDR is 1/2 the input clock therefore HS400 rates clocked at 200Mhz require a 400Mhz SDHC clock.

This showed about a 1.5x improvement in read performance for the eMMC's used on the various imx8m{m,n,p}-venice boards.
