On those chipsets the pins are just a legacy concept. Real interrupts are
messages on corresponding busses or some internal logic of chipset.
Hence interrupt routing isn't anymore board-specific (dependent on layout) but
depends only on configuration.
Rather than attempting to sync real config, ACPI and legacy descriptors, just
use the same interrupt routing per chipset covering all possible devices.
The only part which remains board-specific are LPC and PCI interrupts.
Interrupt balancing may suffer from such merge but:
a) Doesn't seem to be the case of this map on current systems
b) Almost all OS use MSI nowadays bypassing this stuff completely
c) If we want a good balancing we need to take into account that e.g.
wlan card may be placed in a different slot and so would require complicated
balancing on runtime. It's difficult to maintain with almost no benefit.

This existed for ChromeOS but was no longer used with DYNAMIC_CBMEM.

probably a problem in MRC:
- EHCI output failure after sysagent
- no S3
- no MRC cache
- MRC needs watchdog
- less MTRR could be used by some memory map optimisations
Not tested:
- dock (probably doesn't work)
- msata (probably works)
- wwan (probably works)
- mini displayport (probably works)
Blobs:
MRC
VGA Oprom
