x86: irq_remapping: Use irq_alloc/free_hwirq()
The create_irq variants are going away. Use the new interface. The
core and arch code already excludes the gsi interrupts from the
allocation, so no functional change.
This does not replace the requirement to move x86 to irq domains, but
it limits the mess to some degree.
