[U-Boot] am335x: musb: mass storage device issue

[Yegor Yefremov]

My am335x based board doesn't detect USB sticks:

U-Boot 2017.03-rc1 (Feb 13 2017 - 12:46:54 +0100)

CPU  : AM335X-GP rev 2.1

       Quectel, Incorporated UMTS/HSPA Module

U-Boot finds a hub and a 3g modem attached to it, but the USB drive,
that is also attached to this hub won't be detected.

So far I haven't tried to bisect the issue (have to find a working
commit including my board), but the same setup is working for 2014.07
u-boot. Am I the only one or are other am335x based also affected?
