colibri_imx6: fix broken fsl_esdhc_imx conversion

Not all CONFIG_FSL_ESDHC defines were properly replaced with
CONFIG_FSL_ESDHC_IMX, which broke U-boot proper booting on
Colibri iMX6 SoMs.

U-boot is stuck after this message:
Commercial temperature grade DDR3 timings, 64bit bus width.
Trying to boot from MMC1

Fixes: e37ac717("Convert to use fsl_esdhc_imx for i.MX platforms")
