mainboard/google/poppy: Add support for cr50 I2C TPM
1. Add support for using cr50 I2C TPM on poppy. This will not be
enabled until the next build.
2. Also, configure GPIOs for SPI and I2C TPM only if the corresponding
Kconfig options are set.
BUG=b:36265511
TEST=Verified on a reworked board that I2C TPM communication works
fine.
