Ivybridge: fix workaround and enable PAIR
MCHBAR 0x5f10[7:0] should be set to 0x30 for ivybridge
and 0x20 for sandybridge. Move this code to ramstage
and set it per-chipset.
Power Aware Interrupt Routing is supported in ivybridge,
enable it and set fixed priority.
Boot on ivybridge device and read MCHBAR 0x5f10:
mmio_read8 0xfed15f10
0x30
And verify PAIR is enabled (bit4=1):
mmio_read8 0xfed15418
0x24
