USB: EHCI: Add a quirk to skip the suspend during test mode selection

As per the EHCI specification, all the enabled ports are put into
suspend before putting any port in test mode. This is not required
for controllers like MSM Chipidea controller which puts the PHY
into suspend when the port is suspended. The PHY has to be resumed
anyway to send the test pattern. Add a quirk to skip the port suspend
for such controllers.
