intel/bd82x6x: Refactor and complete IRQ routing

Refactor the irq routing to use a single source of truth for consistency.

Add missing routing data for the gigabit ethernet and management engine
devices.

Apply the good old PCI strategy of rotating the list links by one for
each pci device (since most devices use link A this works well).

Also fix small mistake in DIR_ROUTE, the register is 16-bits wide.
If the DIR_ROUTE call ordering was reversed the previous writes would
get overwritten.

With this, the built-in gigabit ethernet works with pci=nomsi in Linux.
