There is a whole bunch of pads being configured by the vendor firmware
that are either unconnected due to unpopulated resistor pads, only
connected to test points for vendor debugging purposes or just used as
strap. Configure them as NC with an appropriate pull to disable the
RX/TX functions.
The pads have been determined by dissecting a dead board.
This patch has been tested thoughroughly on a machine, normally used
productive, to see if any issues arise. No problems occurred at all.

Move the manual calls to fw_config_probe() into the devicetree; the
AUDIO probe is trivial, and the TCSS devices (DMA0, iTBT RP0 & RP1) are
already guarded with probe statements in the baseboard devicetree, so
the code in romstage.c was redundant. The variants seem to have their
USB4 probe statements correct as well, so the manual UPD setting in
mainboard.c was also unnecessary.

A mainboard might want to configure some things differently when a
device is in an unprovisioned state. In the case when fw_config comes
from the Chromium EC, an unprovisioned device will not have a FW_CONFIG
tag in its CBI. This patch will set the fw_config value to
UNDEFINED_FW_CONFIG in the case of an error retrieving the value, as
well as adding a function, `fw_config_is_provisioned()` to indicate the
provisioning status.
BUG=none
TEST=remove fw_config from chromium EC CBI, add code to mainboard to

Move the southbridge_write_acpi_tables declaration from acpi.h to common
lpc_lib.h, as common LPC is always the caller. This removes a duplicate
declaration since all soc/intel devices use common LPC, but not all use
common ACPI. The southbridge_write_acpi_tables function is defined in acpi.c
with the other acpi functions.
Note that this would have the reverse problem if there is ever a non-common
LPC device.

Currently it's not possible to add multiple graphics driver into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics driver can use.
This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel and Aspeed on server platforms or
Intel and Nvidia on consumer notebooks.
The goals are to remove duplicated fill_fb_framebuffer(), to advertise
multiple independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.
Add an implementation in edid_fill_fb that supports registering
multiple framebuffers, each with its own configuration.
As the current code is only compiled for a single graphics driver
there's no change in functionality.
