fsl udc: Fix cable connect/disconnect checkingtegra-9.12.11
On VBUS interrupt irq acknowledges the VBUS interrupt and schedules the work
thread for powering/up down the USB phy and clocks based on the VBUS status.
But, in the work thread instead of checking the VBUS status directly,
rechecking the interrupt status which is already disabled. This is fixed by
checking the vbus status only in the work thread for controlling the power
up/down sequence. Due to the disconnect problem power numbers increased when
there is no USB cable connected to the system.
