Maciej W. Rozycki 4b92cfc444 x86/PCI: Fix ALi M1487 (IBC) PIRQ router link value interpretation
[ Upstream commit 4969e223b1 ]

Fix an issue with commit 1ce849c755 ("x86/PCI: Add support for the ALi
M1487 (IBC) PIRQ router") and correct ALi M1487 (IBC) PIRQ router link
value (`pirq' cookie) interpretation according to findings in the BIOS.

Credit to Nikolai Zhubr for the detective work as to the bit layout.
