Not sure I understood the question correctly but how I think
this should be deployed is:

- A boolean CONFIG_TCG_TIS_SPI_CR50.
- tpm_tis_spi_cr50.c that gets compiled in as part of tpm_tis_spi
when the config option is selected.

I think this would best follow the conventions that are in place
already. Please tell if I got something wrong or if there is some
bottleneck in this framework but this is anyway what I would prefer
with the knowledge I have...
