The IRQ trigger type of Palmas MFD device (tps65913) is low-level
sensitive. The wrong configuration would cause an interrupt storm
when booting the system. Fixing it in DT with appropriate interrupt
type.

This fails as GIC does not support the interrupt flag of 8.

I did not get the interrupt storm and even interrupt is not working on tot.
Two ways to resolve this:
- Change the interrupt flag to 0 from 4. Or
- Remove the nvidia,invert-interrupt; for PMC node.
