Subject: trogdor: Add support for rev1

This patch implements the pin changes needed for Trogdor rev1.
Unfortunately, coreboot has to get the EC and TPM SPI busses compiled
into Kconfig, so we cannot really build a single image that runs on both
revisions. Introduce a Kconfig to handle this instead.
