OMAP4: USB: Fixed tshut reboot issue

Wakeup enable was set for usbb1_ulpitll_dir.usbb1_ulpiphy_dir. This is also
muxed with gpio 86. When a wakeup event was detected as part of the
gpio runtime resume, it set the gpio 86 event causing a tshut irq event.
We now rely on the wakeup from pin usbb1_ulpitll_dat0.usbb1_ulpiphy_dat0 for
USB wakeup events.
