abdc7b8a2d tpm: Convert to use a device parameter
At present many TPM calls assume there is only one TPM in the system and
look up this TPM themselves. This is inconsistent with driver model, which
expects all driver methods to have a device parameter. Update the code to
correct this.

998af31903 sandbox: tpm: Tidy up enums and return values
Use an enum for command values instead of open-coding them. This removes
the need for comments. Also make sure the driver returns proper error
numbers instead of -1.

b9dd4fabbe tpm: add PCR authentication commands support
Add support for the TPM2_PCR_SetAuthPolicy and
TPM2_PCR_SetAuthValue commands.

Change the command file and the help accordingly.

Note: These commands could not be tested because the TPMs available
do not support them, however they could be useful for someone else.
The user is warned by the command help.
