Subject: [PATCH v3 08/15] ARM: dts: am574x-idk: Add pinmux configuration for MMC

From: Sekhar Nori <nsekhar@...com>

Include dra76x-mmc-iodelay.dtsi which has pinmux and IODelay
configuration values for the various MMC modes for am574x SoC
and use it in the pinctrl properties of MMC devicetree
nodes present in am574x-idk.dts.
