The GPIO pins for UART 0 on Fizz are routed to the add-in card slot
and should not be used as a UART device. coreboot is setting the
pins to GPIO Mode but FSP is re-configuring them for Native Mode
and the behavior is unexpected when the kernel tries to initialize
the UART device.
The UART 0 device is PCI function 0 so it needs to be enabled for
other functions to be visible to the OS so it can't just be disabled.
Instead, set the device to PchSerialIoSkipInit so that FSP will not
change the pin state.
BUG=b:73006317
TEST=Tested with add-in card on fizz hardware to ensure the pin state
does not change when FSP runs or the kernel boots.

This change adds a configurable delay in milliseconds before SLP_EN is set in
SLP_SMI for S5. Reason for doing this is to avoid race between SLP and power
button SMIs.
On some platforms (Nami, Nautilus), it was observed that power button SMI
triggered by EC was competing with the SLP SMI triggered by keyboard
driver. Keyboard driver indicated power button press which resulted in
depthcharge triggering SLP_SMI, causing the AP to enter S5. However, the power
button press also causes the EC to send a pulse on PWRBTN# line, which is
debounced for 16ms before an interrupt is triggered. This interrupt was
generated after SLP_SMI is processed which resulted in the device waking back up
from S5.
This change adds a config option SOC_INTEL_COMMON_BLOCK_SMM_S5_DELAY_MS which is
used to add a delay before SLP_EN is set for S5. This change should only affect
CHROMEOS boards as the config option will be 0 in other cases.
