[PATCH 5.3 125/344] ARM: dts: imx7-colibri: disable HS400

[Greg Kroah-Hartman]

From: Stefan Agner <stefan.agner@xxxxxxxxxxx>

[ Upstream commit a95fbda08ee20cd063ce5826e0df95a2c22ea8c5 ]

Force HS200 by masking bit 63 of the SDHCI capability register.
The i.MX ESDHC driver uses SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400. With
that the stack checks bit 63 to descide whether HS400 is available.
Using sdhci-caps-mask allows to mask bit 63. The stack then selects
HS200 as operating mode.

This prevents rare communication errors with minimal effect on
performance:
	sdhci-esdhc-imx 30b60000.usdhc: warning! HS400 strobe DLL
		status REF not lock!
