usb: musb: do not sleep in atomic context
musb_port_reset() is called from musb_hub_control() which in turn holds
a spinlock, so musb_port_reset() is not allowed to call msleep().
With the asynchronous work helpers in place, this is fortunately easy to
fix by rescheduling the reset deassertion function to after the time
when the wait period is finished.
Note, however, that the MUSB_POWER_RESUME bit is only set on AM33xx
processors under rare conditions such as when to another driver
reporting an error during suspend. Hence, this didn't hit me yet in
normal operation.
