Update this code to support CONFIG_BLK. Each USB storage device can have one or more block devices as children, each one representing a LUN (logical unit) of the USB device.
Note that I accidentally tested some other patches in the wrong place today, and found that this patch prevents my USB SD card reader from working when attached to Jetson TK1. I get:
U-Boot 2016.03-rc3-00056-gb3601815cf72 (Mar 14 2016 - 11:54:53 -0600)

Device NOT ready Request Sense returned 02 3A 00 ### ERROR ### Please RESET the board ###
(The Request Sense error happens even in the passing cases, but in those cases the overall "usb start" operation succeeds, and then USB storage access does actually work. I guess my reader is a little slow to initialize or something).
The patch immediately before this one works fine.
Can you reproduce this? If not, let me know and I'll investigate further.
