[PATCH v2] ARM: dts: vf610-twr: Add support for sdhc1

From: Cosmin Stoica <cosminstefan.stoica at freescale.com>

The kernel was not able to boot from SD card because sdhc support
was not present into the dts.

A new entry for sdhc1 was added for vf610-twr board based on the
compatible entry present on imx53.

After applying these changes, the kernel is able to boot successfully
from SD card.

Changes v1-v2:
According to Shawn Guo's comments:
- moved esdhc1 node before fec0 in board dts file;
- reformatted clocks line;
- removed duplicate property (bus-width) in dtsi file.
