[PATCH 1/2] dt-bindings: soc: imx: Add fsl,eim-bus

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@nxp.com>

Add the fsl,eim-bus compatible strings for i.MX51 variants.

These compatibles are only intended for existing legacy chips (more than 15
years old) and will not be used for new device trees.

Fix below CHECK_DTBS warnings
arch/arm/boot/dts/nxp/imx/imx53-ard.dtb: /eim-cs1@f4000000: failed to match any schema with compatible: ['fsl,eim-bus', 'simple-bus']
