[U-Boot] [PATCH v2] usb: increase non-bulk timeout for slow chipsets.

[Jason]

Remy,

I neglected to include you in my original submission, could you please
take a look at this for u-boot-usb?  Original email is here [1].  And
the commit I'm referring to is here [2].

The dreamplug platform must pull it's uImage from a usb attached microSD
card.  They are completely unbootable without this patch.  However, this
is a u-boot-wide change and I'm not familiar enough to say this won't
break something else.  Your insight would be appreciated.

thx,

Jason.
