x86: put irq_2_iommu pointer into irq_desc
when CONFIG_HAVE_SPARSE_IRQ preallocate some irq_2_iommu entries, and use get_one_free_irq_2_iomm to get new one and link to irq_desc if needed. else will use dyn_array or static array. v2: <= nr_irqs fix Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
