[PATCH 5.10 95/95] mmc: sdhci-esdhc-imx: Convert the driver to DT-only

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Fabio Estevam <festevam@xxxxxxxxx>

commit 854a22997ad5d6c9860a2d695c40cd4004151d5b upstream.

Since 5.10-rc1 i.MX is a devicetree-only platform, so simplify the code
by removing the unused non-DT support.
