The host bridge PCI device ID can be changed by the firmware. There
is no documentation about it, though. There's 'official' IDs, which
appear in spec updates and Windows drivers, and 'mysterious' IDs,
which Intel doesn't want OSes to know about and thus are not listed.
For the sake of completeness, add the PCI device IDs for Clarkdale.
Though coreboot only supports Arrandale, both of them are Ironlake.
It is possible that the Management Engine handles changing the PCI
device ID, which would not happen when using a broken ME firmware.

Inteltool is GPLv2 licensed so all files that link to it should be GPLv2
by default. In addition, the contents of several of these headers were
originally moved directly from gpio_groups.c, which is explicitly marked
as GPL-2.0-only.

EBG (Emmitsburg) PCH is used in Intel SPR-SP chipset.
Its datasheet is Intel doc# 606161.
Add Intel Emmitsburg PCH GPIO pin definitions.
Also common code change is made to support Intel Emmitsburg PCH:
a. Instead of 2 PAD registers per GPIO, it has 4 PAD registers.
b. The register address space may not be contiguous from one GPIO
group to the next GPIO group.

Fix issue where registers always seem to contain their own offset.
After writing the desired register into SIRI, the requested data is
returned in SIRD. This register is 4 bytes after SIRI, commonly 0xA4.
Tested on TGL-H (SATA SIR registers are common), genuine data is
returned.

Adds the ability to output MSRs dump for the specified range of CPU
cores. This makes it easier to reverse engineer server multicore
processors using the inteltool utility.
The range is set using --cpu-range <start>[-<end>] command line option:
$ sudo ./inteltool -M --cpu-range 0-7
$ sudo ./inteltool -M --cpu-range 7-15
$ sudo ./inteltool -M --cpu-range 32
$ sudo ./inteltool -M will print a register dump for all cores, just
as before.

Print whether the SOC supports TME/MKTME. If the SOC supports the
feature, print the status of enable and lock bit from TME_ACTIVATE
MSR. -t option prints this status.
Sample output:
If TME/MKTME is supported:
============= Dumping INTEL TME/MKTME status =============
TME supported : YES
TME locked : YES
TME enabled : YES

If TME/MKTME is not supported:

Right now IGD is hard coded to 0:2.0 and if that
device is there, it is blindly used, even if it is
not a graphics device. Look at the PCI class to make
sure we're not using the wrong device.
