MLK-17380-4 usb: host: xhci: add EH SINGLE_STEP_SET_FEATURE Test for USB2
This function is similar with EHCI's, but implemented using XHCI.
The USB2 host needs to send SETUP packet first, then wait 15
seconds before DATA (IN) + STATUS stage.
It is needed at USB Certification test for Embedded Host 2.0, and
the detail is at CH6.4.1.1 of On-The-Go and Embedded Host Supplement
to the USB Revision 2.0 Specification
