Robert Baldyga cf54772b91 usb: dwc2: call dwc2_is_controller_alive() under spinlock
This patch fixes the following problem: data transmission in direction
IN break unless the GSNPSID register access is done with spinlock held.
This issue occurs at least in Exynos4412 SoC, probably in many SoC's
from Exynos familly.

The problem is described here:
