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.
