Fenghua Yu 68c1b89cf5 iommu/vt-d: Print x2apic opt out info instead of printing a warning 
BIOS can set up x2apic_opt_out bit on some platforms, for various misguided
reasons like insane SMM code with weird assumptions about what descriptors
look like, or wanting Windows not to enable the IOMMU so that the graphics
driver will take it over for SVM in "driver mode".

A user can either disable the x2apic_opt_out bit in BIOS or by kernel
parameter "no_x2apic_optout". Instead of printing a warning, we just
print information of x2apic opt out.
