The Linux driver automatically can detect and enable UHS, HS200, HS400 and HS400_ES automatically without extra flags being placed into the device tree. Right now, for U-Boot to use UHS, HS200 or HS400, the extra flags are needed in the device tree. Instead, go through the esdhc_soc_data flags and enable the host caps where applicable to automatically enable higher speeds.

Applied to u-boot-imx, master, thanks !
