Naga Chumbalkar 42f0efc5aa 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

 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:
