mainboard/google/eve: Set UART0 to skip initialization in FSP
Set UART0 to "PchSerialIoSkipInit" so the pins for this device are not
set back to native mode by FSP when configured as GPIO input by coreboot.
Now that FSP is not touching the pins I also removed the workaround to
reconfigure the pins after FSP.
BUG=b:35647877
BRANCH=none
TEST=Verify that GPP_C8-GPP_C11 are configured as GPIO input once the OS
is booted and they are not set back to native function by FSP.
