Commit Message

Winkler, Tomas Sept. 28, 2018, 10:30 p.m. UTC 
Factor out TPM 1.x commands calculation into tpm1-cmd.c file.
and change the prefix from tpm_ to tpm1_.
No functional change is done here.

---
V2-V3: Rebase
V4: 1. Remove the licence statement it's already covered by SPDX.
    2. Add kdoc to tpm1_calc_ordinal_duration().
V5: Adjust the kdoc to the new standard.

The original code in the nuvoton driver does not differentiate between 
TPM 1.2 and TPM 2.0 as it does in tpm_tis_core.c.  Before making any 
changes, I would first fix it, so that it could easily be backported. 
Only then do the refactoring

Thanks & Regards,
