Longfang Liu 643a4df7fe USB: ehci: fix an interrupt calltrace error 
The system that use Synopsys USB host controllers goes to suspend
when using USB audio player. This causes the USB host controller
continuous send interrupt signal to system, When the number of
interrupts exceeds 100000, the system will forcibly close the
interrupts and output a calltrace error.

When the system goes to suspend, the last interrupt is reported to
the driver. At this time, the system has set the state to suspend.
This causes the last interrupt to not be processed by the system and
not clear the interrupt flag. This uncleared interrupt flag constantly
triggers new interrupt event. This causing the driver to receive more
than 100,000 interrupts, which causes the system to forcibly close the
interrupt report and report the calltrace error.

so, when the driver goes to sleep and changes the system state to
suspend, the interrupt flag needs to be cleared.
