Processor graphics is disabled on, for example, the C222 and C224
chipsets.
The change to resource assignment in northbridge.c prevents the following
warning that occurs when the IGD is disabled:
> skipping PCI: 00:00.0@3 fixed resource, size=0!
Tested on a Supermicro X10SLM+-F, which has the IGD disabled by the
chipset. The graphics memory is reclaimed and no issues were observed.
Also tested on an ASRock H81M-HDS. This board has an IGD, but no
regressions were observed.

The existing code sets DEVEN with the intention of enabling the IGD and
Mini-HD audio. However, according to the datasheet [1] and some testing
on hardware, the bits in DEVEN are set by default if and only if the
straps/fuses say the device should be enabled. To illustrate this, here
are a few initial values of DEVEN on some Haswell systems:
Supermicro X10SLM+-F: 0x0000002d
ASRock H81M-HDS: 0x00000039
Acer C720: 0x000000b1
On the X10SLM+-F, the IGD is disabled by default, and PEG10 & PEG11
are enabled by default. On the C720, the PEG devices are all disabled
by default, while the IGD and Mini-HD audio are already enabled.
There are two issues that result from the existing behaviour: PEG
devices are unconditionally disabled, and devices are set as enabled
when it's not actually possible to enable them.
So, don't touch the DEVEN register at this stage, as there are no
benefits.
Interestingly, on an Acer C720 (Google Peppy), a PCI device 00:04.0
appears. It is a thermal sensor. `powerstat` was used to measure idle
power usage over 30 minutes under Debian GNU/Linux 9.6. There was no
change in reported power draw.

This allows devices to be properly disabled when they are set to `off`
in the devicetree, or when a device has its `enabled` property set to
false.
A message is printed stating that a device is being disabled, even if
it was already disabled via DEVEN. However, it could be useful to have
this information, so such messages are kept.
The device 00:04.0 is a thermal sensor on the Acer C720, but it has not
been named as such in this patch. This is because the public datasheets
never formally acknowledge what the device is, and how it might differ
across platforms.
Tested on a Supermicro X10SLM+-F. The Mini-HD audio is disabled now,
silencing a warning from Linux.
Also tested on an Acer C720 (Google Peppy). Disabling "device 4" from
devicetree.cb works.
Also tested on an ASRock H81M-HDS. For this device, and all other test
devices, there were no regressions observed.

Commit 8cf8aa2 [ec/google/chromeec: Use common MEC interface]
changed the return mechanism for the checksum on reads/writes
for MEC devices, but incorrectly handled the passed-in csum
parameter by not dereferencing. This led to the returned csum
value always being zero, which causes all EC commands with non-
NULL data_in to fail with a checksum error.
Fix this by storing the returned checksum in a temp variable,
and only assigning to csum when the pointer isn't NULL;
Test: build/boot google/chell, verify EC hello command succeeds,
keyboard backlight turned on at boot.

The H81 chipset is the only non-LP Lynx Point chipset with 6 PCIe root
ports, all others have 8 [1]. The existing PCIe code assumed that all
non-LP chipsets had 8 root ports, which meant that port 6 would not be
considered the last root port on H81, so `root_port_commit_config()`
would not run. Ultimately, while PCIe still worked on H81, all the root
ports would remain enabled, even if disabled in the devicetree.
Also, remove `PCI_DEVICE_ID_INTEL_LYNXPOINT_MOB_DESK_{MIN,MAX}`, as they
are unused, and the MAX constant is incorrect.
Interestingly, this fixes an issue where GRUB is unable to halt the
system.
Tested on an ASRock H81M-HDS. The root ports disabled in the devicetree
do indeed end up disabled.
