usb: host: pehci: Add USB core changes needed by PEHCI

Browse Source 
A user can initiate host compliance tests or suspend/resume
requests over the ISP1763A USB Host controller by issuing
IOCTLs on the pehci device.
Add necessary changes in USB core to support these requests.
These changes are taken from the 1.0.6.0 version of ST-E pehci
driver present at: http://www.box.net/shared/static/o5esh7r14q.zip
along with the fixes for checkpatch errors and removal of unused
variables.
