Subject: [PATCH] pci/dmar: add __init annotation to dmar_ir_support()

dmar_ir_support() references dmar_tbl which is annotated with
__initdata. The only caller of dmar_ir_support() is
intr_remapping_supported() also annotated with __init.

WARNING: drivers/pci/built-in.o(.text+0xa110): Section mismatch in
reference from the function dmar_ir_support() to the variable
.init.data:dmar_tbl
The function dmar_ir_support() references
the variable __initdata dmar_tbl.
This is often because dmar_ir_support lacks a __initdata
annotation or the annotation of dmar_tbl is wrong.
