Subject: mmc: sdhci-esdhc-imx: Convert to pinctrl_select_default_state()
Git-commit: 2480b72071b2d4be5922e2e7639303bd2d64195e
Patch-mainline: v5.6-rc1
References: jsc#SLE-16106

Let's drop the boilerplate code for managing the default pinctrl state and
convert into using the new pinctrl_select_default_state().
