[PATCH] ARM: dts: imx: Fix the iim compatible string

[Fabio Estevam]

Per imx-iim.yaml, the compatible string should only contain a single
entry.

Change it accordingly to fix the following dt-schema warnings:

efuse at 83f98000: compatible: ['fsl,imx51-iim', 'fsl,imx27-iim', 'syscon'] is too long
