The GPIO controllers on PolarFire SoC were based on the "soft" IP CoreGPIO, but the inp/outp registers are at different offsets. Add compatible to allow for support of both sets of offsets. The soft core will not always have interrupts wired up, so only enforce them for the "hard" core on PolarFire SoC.
