IRQ_DOMAIN_HIERARCHY is not user-configurable, but supposed to be

GPIO_THUNDERX is the only user of "depends on IRQ_DOMAIN_HIERARCHY".
This means, we can not enable GPIO_THUNDERX unless other drivers
select IRQ_DOMAIN_HIERARCHY elsewhere. This is odd. Flip the logic.

IRQ_DOMAIN_HIERARCHY is set as a result of ARCH_THUNDER (this SoC
hardware), so it actually works as-is. That said, this looks like a
reasonable improvement, and will allow the COMPILE_TEST to enable it, so...

Say yes here to support the on-chip GPIO lines on the ThunderX
