x86: Embedd irq_2_iommu into irq_cfg
That interrupt remapping code is x86 specific and tied to the io_apic code. No need for separate allocator functions in the interrupt remapping code. This allows to simplify the code and irq_2_iommu is small (13 bytes on 64bit) so it's not a real problem even if interrupt remapping is runtime disabled. If it's compile time disabled the impact is zero.
