Julius Werner 8db7e6702b libpayload: usbmsc: Add small delay during initialization to fix CZ60
We found that some SanDisk Cruizer Glide CZ60 sticks (confirmed on 16GB
and 64GB versions) have a problem responding to our first GET_MAX_LUNS
request right after they received their SET_CONFIGURATION. They will
continually return a NAK until the host gives up (which is 2
user-noticable seconds for us). Adding a small delay of about 15us seems
to be enough to fix the issue, but let's do 50 to be save.

Confirmed with both MT8173 and Intel LynxPoint XHCI controllers.

BRANCH=None
BUG=chrome-os-partner:45473
TEST=No notable delay before detecting stick on Oak and Falco.
