x86, ioapic: Print IR_IO_APIC_route_entry when IR is enabled
When IR (interrupt remapping) is enabled print_IO_APIC() displays output according
to legacy RTE (redirection table entry) definitons:
NR Dst Mask Trig IRR Pol Stat Dmod Deli Vect:
00 00 1 0 0 0 0 0 0 00
01 00 0 0 0 0 0 0 0 01
02 00 0 0 0 0 0 0 0 02
03 00 1 0 0 0 0 0 0 03

05 00 1 0 0 0 0 0 0 05
06 00 1 0 0 0 0 0 0 06
...
The above output is as per Sec 3.2.4 of the IOAPIC datasheet:
82093AA I/O Advanced Programmable Interrupt Controller (IOAPIC):
http://download.intel.com/design/chipsets/datashts/29056601.pdf
Instead the output should display the fields as discussed in Sec 5.5.1
of the VT-d specification:
(Intel Virtualization Technology for Directed I/O:
http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf)
After the fix:
