tpm(4): Add the STANDARDS and HISTORY sections.
Also, link to the homepage of the BSSSD project, which developed
the original driver.

Questions:
- Are we sure that tpm(4) is implementing TPM specification version 1.2? [[ https://lists.freebsd.org/pipermail/freebsd-hackers/2017-February/050584.html | This thread from hackers@ (2017-02) ]] suggests that not really.
- Are we sure that tpm(4) is //not// implementing TPM specification version 2.0? If so then maybe we could mention it in the manual page. [[ https://lists.freebsd.org/pipermail/freebsd-hackers/2017-February/050584.html | This thread from hackers@ (2017-02) ]] suggests that version 2.0 is not implemented.
