Allow to select the primary graphics device between the IGD and the
external PCIe GPU depending on the ONBOARD_VGA_IS_PRIMARY config.
The option sets the priority only. This means that if a high priority
is set for an external PCI device and it is not connected/not enabled,
then the device with a lower priority will be used, in our case it is
IGD.

Since the raw GPIO MMIO register access is now only used inside the

moved to that block to reduce the visibility and enforce the usage of
the functions provided by the gpio_banks block.

No need to do raw GPIO MMIO accesses when basically the same
functionality can be achieved by using existing APIs. Using the existing
GPIO API instead of raw GPIO MMIO register accesses allows containing
all direct GPIO MMIO accesses inside the common AMD GPIO code which will
be done in subsequent patches. Since the value parameter of gpio_set is
int, change the type of the val parameter of drive_scl to int as well
even though I'm not sure why a signed integer was used for this in the
common GPIO API. Since program_gpios already configures the SCL GPIOs as
outputs, gpio_set can be used in drive_scl which only sets the output
value, but doesn't configure the direction.
TEST=The waveform on the SCL pin of I2C3 on a barla/careena Chromebook
looks similar to the same as before during the reset_i2c_peripherals
call, but due to the additional overhead of the read-modify-write to the
GPIO register instead of just a write, the pulse width gets about 50%
longer. Since the udelay call in drive_scl still has an open TODO to
make this configurable and the pulses being longer is in the safe side,
this side-effect can be addressed in a follow-up patch.

drive_scl in soc/amd/common/block/i2c/i2c.c writes the raw GPIO MMIO
configuration register and drives it as output, so don't initially
configure the GPIO as input with no pull up/down. This is a preparation
to use the common AMD GPIO access functions instead of the raw register
accesses, since the gpio_set function only sets the output value, but
doesn't reconfigure the direction. Using gpio_output there instead would
reconfigure the direction as well, but would result in doubling the
number of MMIO accesses, so just configure the GPIOs correctly right
away to avoid that.

All KBLRVP variants select the `INTEL_LPSS_UART_FOR_CONSOLE` Kconfig
option and set `UART_FOR_CONSOLE` to `2`, so that UART #2 is used as
coreboot console. However, the LPSS console driver requires the LPSS
UART to be memory-mapped (and not I/O-mapped, like Super I/O UARTs).
KBLRVP variant RVP8 uses `PchSerialIoLegacyUart` for UART #2, which
makes FSP-S configure UART #2 in legacy, I/O-mapped mode. This most
likely results in the UART console not working after FSP-S has run.
This change updates RVP8 to use `PchSerialIoSkipInit` for UART #2, like
the other KBLRVP variants do.
