Bug #652: autoport fails if board lacks SATA controller and unsupported PCI/USB
(Apple MacBookPro 11,4 / Crystal Well)

----------------------------------------
This Haswell board comes with a Samsung PCIe AHCI SSD on a autoport
`Unsupported PCI device 8086:0d01` (Apple Slot) which is probably muxed with
the Thunderbolt controller `Unsupported PCI device 8086:0d05`. There is also no
native intel SATA controller available on this board.

Adding `RegisterPCI(0x8086, 0x0d0c, GenericPCI{})` to line 141 in `haswell.go`
within `/* CPU HD Audio */` fixes the `8086:0d0c` device not being Unsupported.
However I have no idea how to add those Unsupported `PCIe 00:01.0 / 00:01.1`
`0d01 / 0d05` devices to the code, but I was able to remove the SATA detection
which fails at line 194 `sata_port_map...`in `lynxpoint.go` by removing most
SATA related *.go code.
After that autoport will progress but hang on USB not being correctly detected
so I also hacked USB out of *.go files leaving me with half a build which
doesn't build... The elephant in the room for this board support is probably
adding coreboot memory init support for the soldered RAM config but first
things first?
Digging further it seems that `inteltool` misses crucial regions, which may be
the reason the PCIe and USB devices are unsupported detected?

With the added logs it is possible to test/build autoport on a other machine
using:
`./autoport --input_log=mbp114logs --coreboot_dir=../..`
