mb/google/poppy: do early pad configuration in early bootstage

Do early pad configuration in early bootblock before console init, to
make the console work as early as possible. The board does not do any
other gpio configuration in bootblock, so this should not influence
behaviour in a negative way (e.g. breaking overrides).
