mb/google/puff: Set early GPIOs to enable bootblock console
Without the PCH UART GPIOs set early, there is no serial console output until ramstage. Add them to the early GPIOs for all puff variants. TEST=build/boot google/puff (wyvern) with serial console enabled, verify console output starts in bootblock.
