Running TF-A 2.0 and later seems to cause a regression on HiKey 620.

NOTICE: BL2: v2.0(release):v2.0
NOTICE: BL2: Built : 17:41:23, Dec 17 2018
NOTICE: acpu_dvfs_set_freq: set acpu freq success!ERROR: CMD1 failed after 100 retries
ERROR: BL2: Failed to load image (-5)

The reason seems to be that during emmc enumeration when BL2 sends the command
OCR_SECTOR_MODE | OCR_VDD_MIN_2V7 | OCR_VDD_MIN_1V7

it for some reason takes some more time to get a reply. So a delay with
mdelay(1), seems to not be enough any longer and therefore we increase it to
mdelay(10) instead which makes the device boot as expected again.
