These are defined for __SIMPLE_DEVICE__ when PCI
enumeration has not happened yet. These should not
really try to probe devices other than those on bus 0.
It's hard to track but there maybe cases of southbridge
being located on bus 2 and available for configuration, so
I rather leave the code unchanged. Just move these out of
arch/io.h because they cause build failures if one attempts
to include <arch/pci_ops.h> before <arch/io.h>.
There are two direct copies for ROMCC bootblocks to
avoid inlining them elsewhere.

Extend its functionality so we can also check that BL31 is loaded in
a manually reserved area, and fail early if the range is not protected.

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.

The feature is used to enable PCI MMIO accesses behind
PCIe links (or bridges) before PCI enumeration has been
completed.
Add the feature for bootblock, verstage and postcar, it
is required with add-on PCIe serial cards for early
console output. It's up to the board specific code to
configure PCIe root port prior to calling console_init()
for this to work.
Remove feature from ramstage, it bypasses any resource
allocations and bus number assignments.
For the moment PCI configuration support before ramstage
is available only on ARCH_X86.
Also switch from device_t to pci_devfn_t.

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.

Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the
"Debug" menu. It turned out, though, that the code looks rather generic.
No need to hide it in soc/intel/.
To not bloat src/Kconfig up any further, start a new `Kconfig.debug`
hierarchy just for debug options.
If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.
