Initialize the two GPIOs of the SoC UART if it's used for serial console
to be sure that the I/O mux is configured correctly without having to
rely on the bootblock_mainboard_early_init call to do this. This brings
Stoneyridge more in line with the other AMD SoCs. Since this code will
be factored out to the common AMD SoC code in a follow-up patch, the
function prototype is added to southbridge.h instead of creating a new
uart.h header file.

Gmeet video call, it uses the hardware accelerated encoder as per
the expectation. But, as soon as another system connects to the call,
the immediate fallback observed from hardware to software encoder.
Due to this, Gmeet resolution dropped from 720p to 180p.

Configure the Intel iGPU as primary video adapter if enabled according
to EEPROM settings. The default is to use the ASPEED BMC as primary
video adapter, which only has a VGA output and the remote KVM output.
For now, use the FSP GOP driver to light up the iGPU. There are several
issues with libgfxinit on the Hermes, probably due to the unusual setup
of the iGPU's display outputs. They are routed to a mezzanine connector
for a piggy-back sub-board, of which there are two models. The Poseidon
piggy-back has two DisplayPort outputs and an HDMI output coming from a
MegaChips LSPCON. The Avalanche piggy-back routes all three DisplayPort
outputs from the iGPU into a FPGA, which acts as a DisplayPort sink.
Note that the FSP GOP only initializes at most 2 iGPU display outputs.
However, all three outputs function properly once OS (Windows, Linux)
graphics drivers take over.
Additionally, update the config file that Prodrive uses to build
coreboot images so that the iGPU can be used as primary.
TEST=Verify that the iGPU's outputs work properly in pre-OS, Windows and
Linux, on both the Poseidon and Avalanche piggy-backs.

When the GSC is ready for the next transaction, it triggers a
GSC_AP_INT_ODL (active low) pulse with 100us duration to notify the AP.
Currently the TPM IRQ is configured as EDGE_RISING. Changing it to
EDGE_FALLING would speed up each register access by 100us. On Kingler,
this saves 20ms for the boot time (0.93s -> 0.91s).
