Revert "USB: dwc3-msm: Enable power event irq in case of host bus suspend"

Browse source 
Commit 3dd2172dfecc ("USB: dwc3-msm: Enable power event irq in case of
host bus suspend") is added to enable power_event_irq during host bus
suspend. This is to map MPM pin for DM to power_event_irq to wakeup during
system suspend in host mode. Currently MPM driver has support for mapping
multiple MPM pins to single IRQ. Hence it is not required to enable
power_event_irq during host bus suspend.
