[PATCH 3.16.y-ckt 096/180] usb: musb: use new USB_RESUME_TIMEOUT

[Luis Henriques]

3.16.7-ckt11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felipe Balbi <balbi@xxxxxx>

commit 309be239369609929d5d3833ee043f7c5afc95d1 upstream.

Make sure we're using the new macro, so our
resume signaling will always pass certification.

Based on original work by Bin Liu <Bin Liu <b-liu@xxxxxx>>

Cc: Bin Liu <b-liu@xxxxxx>

[ luis: backported to 3.16:
  - only two msecs_to_jiffies() invocations
  - adjusted context ]
