====================
ATU and VTU irq fixes
Further testing and code review found two sets of bugs.
Core review found a cut/paste error in the irq setup code.
A board which does not have an interrupt line from the switch to the
SoC, and experiancing an EPROBE_DEFER throw a splat when the ATU irq
was freed but never registered.
v2: Fix typ0 chip->chip->vtu_prob_irq to chip->vtu_prob_irq
0-day compile testing.
