Duncan Laurie 3879ef49ea mb/google/fizz: Skip FSP init for UART 0 
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.
