This means that any PCIe device placed in a PEG slot should now work.
During S3 resume, link training sometimes does not complete before
device enumeration. However, no tangible issues have been observed.
Fixing it would introduce a rather large delay in S3 resume.
There are a few minor shortcomings:
- Using PEG for display output is not yet supported.
- Only PEG2 is supported. An extra (unknown) training sequence is said to
be needed for PEG3.
- The ACPI _PRT method is not yet generated, so legacy interrupt routing
doesn't work for devices with multiple functions.
Tested on an ASRock H81M-HDS. Using a Radeon HD 6450 graphics card works
under GNU/Linux, with PRIME [1]. An x1 PCIe card was also tested in the
PEG slot, and it appears functional.

If PCIe root port `n` is disabled, then `rpc.ports[n - 1]` remains NULL.
The existing Lynx Point systems probably don't end up dereferencing
NULL pointers this way. However, it might occur on a system using
Flexible I/O to remap PCIe root ports to other functions.

The existing SATA ACPI code for Lynx Point implements some methods and
devices, but not completely. These methods are optional and only used in
IDE mode. The code was likely copied from bd82x6x, where it has since
been removed.
As a result, many remarks produced by iasl about unreferenced objects
are eliminated.

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`

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.
