irqchip/al-fic: make AL_FIC depend on HAS_IOMEM

Browse Source 
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common than
PCI devices.  Hence it could have a fully functional s390 kernel with
CONFIG_PCI=n, then the relevant iomem mapping functions [including
ioremap(), devm_ioremap(), etc.] are not available.

Here let AL_FIC depend on HAS_IOMEM so that it won't be built
to cause below compiling error if PCI is unset:

------
ld: drivers/irqchip/irq-al-fic.o: in function `al_fic_init_dt':
irq-al-fic.c:(.init.text+0x76): undefined reference to `of_iomap'
ld: irq-al-fic.c:(.init.text+0x4ce): undefined reference to `iounmap'
------
