[Philipp Deppenwiese (Code Review)]

Hello build bot (Jenkins),

drivers/pc80/tpm: Refactor init_tpm() implementation

Move the TPM deactivate command after the tis_init()
function in order to ensure that there is a TPM which
can be used.

Add additional doc for CONFIG_NO_TPM_RESUME kconfig option
which is mainly used by chromebooks.

Add TPM_PcrRead command for TPM state retrieval by calling
it. Now the TPM state is logged. Also if TPM deactivate is
enforced and something is wrong it will jump directly to
the error handling.
