[PATCH v2 2/4] mmc: sdhci-esdhc-imx: add 1-bit bus width support

ziniu.wang_1

From: Luke Wang <ziniu.wang_1@nxp.com>

Add sdhci_get_property() call to parse common SDHCI DT properties,
including "bus-width = <1>" which sets SDHCI_QUIRK_FORCE_1_BIT_DATA
quirk for 1-bit data bus width configuration.

Remove the duplicate "no-1-8-v" property parsing since
sdhci_get_property() already handles it.
