USB: android: Remove PM QOS request during cable disconnect

USB android driver is registering for PM QOS by adding PM QOS request
with request type to PM_QOS_REQ_AFFINE_IRQ and irq number. Then pm_qos
driver sets affinity_notify callback for the irq to get notification.
The same irq will be used for host mode with different irq handler.
When host cable is disconnected, USB driver removes hcd and deregisters
host irq handler by calling free_irq(dev_id). Here irq manager is
throwing warning because driver is registered qos notifier and
calling free_irq for this irq.

Fix this by adding support for removing PM QOS request during
disconnect/suspend and add back again on USB connect.
