That does allow it to boot, however.... it breaks USB.

Can you try with only IRQ_TYPE_EDGE_RISING as you are using GIC interrupts  where IRQ_TYPE_EDGE_FALLING may not be supported

With this change, and with either EDGE_RISING or EDGE_BOTH in the lenovo yoga c630 dts, it does indeed boot.  Leaving LEVEL_HIGH in the c630, it does also boot, but there is a delay of about 30 seconds (I'm assuming interrupt storm?) during the boot.
