63af92e837 tpm: Allow disabling platform hierarchy with TPM2
With TPM2 we don't actually lock the TPM once verified boot is finished.
Instead we disable the platform hierarchy which serves the same purpose.
Add an implementation of this so we can safely boot into the kernel.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

e926136bb2 tpm: use more than sha256 on pcr_extend
The current tpm2_pcr_extend is hardcoded using SHA256.
Let's make the actual command to the TPM2 configurable so we can support
a wider range of algorithms and keep the current command line as-is i.e
limited to SHA256 only

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.

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.
