Anand Gadiyar 572538dee7 USB: ehci-omap: Fix resume failures after bus suspend
An undocumented "feature" in the OMAP3 EHCI controller causes
suspended ports to be taken out of suspend when the USBCMD.Run/Stop
bit is cleared (this bit is normally cleared when ehci_bus_suspend
is called).

This "feature" breaks suspend-resume if the root-hub is allowed
to suspend. (The controller thinks it is in resume, and the PHY
thinks it is still in suspend).

There is an undocumented register bit that can be used to disable
this feature and restore normal behavior. Set this bit so
suspend-resume can work normally.

Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs.
