Commit Message

For boards that use power-domains' power-supplies that need interrupts
to work (like regulator over i2c), set GENPD_FLAG_IRQ_ON.
This will tell genpd to adjust accordingly. Currently it "only" sets the
correct suspend/resume callbacks.

This fixes suspend/resume on imx8mq-librem5 boards (tested) and
imx8mq-evk (by looking at dts) and possibly more.
