This patch prepares the tcgbios.c file for extension with TPM 2 specific code by:
o prefixing all TPM 1.2 specific functions with tpm12_ o where necessary, introduce switch statements in tpm_ -
prefixedfunctions;
here we branch into TPM versions specific code o introduce tpm_ - prefixed functions where necessary; mostly in
those
cases where tpm12_ functions are too large and where the tpm_
function
then only holds the switch statement o leave FIXMEs where we need to write TPM 2 specific code;
subsequent patches
will replace those FIXMEs

I find these "case TPM_VERSION_NONE:" clauses to be a little confusing, both in this patches and the later patches, because I don't think any of these additional code paths are reachable. I think it would be better to just have the branches that are active (ie, v1.2 and v2).
I know. The 'enum' forced this. So I'll remove these then and make TPM_VERSION_NONE etc. individual #define's.
