[U-Boot] [PATCH v2] mx6ul_evk: Remove CONFIG_SUPPORT_EMMC_BOOT

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at nxp.com>

mx6ul_evk does not come with a eMMC populated, so we should not
define CONFIG_SUPPORT_EMMC_BOOT as it causes SPL to not be able
to boot some brands of SD cards, such as SanDisk microSD HC - 8GB:

U-Boot SPL 2016.05-rc1-28384-g108f841 (Apr 19 2016 - 11:19:11)                 
Trying to boot from MMC1                                                       
spl: mmc block read error                                                      
SPL: failed to boot from all boot devices                                      
### ERROR ### Please RESET the board ###

When CONFIG_SUPPORT_EMMC_BOOT is defined spl_boot_mode() returns
MMCSD_MODE_EMMCBOOT, so remove this option to have a reliable boot
via SD card.
