Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

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.
Tested on an ASRock H81M-HDS and an Acer C720 (Google Peppy). No issues
presented themselves.

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.
Tested on an ASRock H81M-HDS and an Acer C720. No issues with SATA
were observed.
