gpio: sifive: select IRQ_DOMAIN_HIERARCHY rather than depend on it

This is the only driver in the kernel source tree that depends on
IRQ_DOMAIN_HIERARCHY instead of selecting it. Since it is not a
visible Kconfig symbol, depending on it (expecting a user to
set/enable it) doesn't make much sense, so change it to select
instead of "depends on".
