Some TPM 2.0 chips offer extra capabilities. This patch adds additional
configuration options to the wolftpm package, so such capabilities can
be available to the user. For example, the STMicroelectronics ST33 and
Nuvoton NPCT750 both offer secure GPIO. Due to chip differences, wolfTPM
requires explicit configuration options to enable the extra capabilities.

Hi Thomas,

This patch is ready for review. Thanks to Fabrice for the good feedback.

ps: I am unable to enter patchwork after password reset, so v4 still 
holds new status.

Regards,
Dimi
