x86/devicetree: Fix device IRQ settings in DT

IRQ parameters for the SoC devices connected directly to I/O APIC lines
(without PCI IRQ routing) may be specified in the Device Tree.

Called from DT IRQ parser, irq_create_fwspec_mapping() calls
irq_domain_alloc_irqs() with a pointer to irq_fwspec structure as @arg.

But x86-specific DT IRQ allocation code casts @arg to of_phandle_args
structure pointer and crashes trying to read the IRQ parameters. The
function was not converted when the mapping descriptor was changed to
irq_fwspec in the generic irqdomain code.

Fixes: 11e4438ee330 ("irqdomain: Introduce a firmware-specific IRQ specifier structure")
