add sm3 256 hash support, so TPM2 chips which report
5 pcrs with sm3 hash do not fail with:

  u-boot=> tpm2 autostart
  tpm2_get_pcr_info: too many pcrs: 5
  Error: -90

Now that the enum includes TPM2_ALG_INVAL, use that name in the
code.

TPM2_PCR_Allocate command is required to reconfigure a TPM device
to enable or disable algorithms in run-time, thus this patch introduces
the implementation of PCR allocate APIs and adds related cmd functions
for testing.

To test the feature, ensure that TPM is started up.
Run pcr_allocate command to turn on/off an algorithm, multiple calls
are supported and all changes will be cached:
`tpm2 pcr_allocate <algorithm_name> <on|off>`
Run startup command with argument 'off' to shutdown the TPM.
`tpm2 startup TPM2_SU_CLEAR off`
Reboot the board via `reset` to activate the changes.

TPM2_shutdown command is sharing same structure and logics with
TPM2_startup, thus this patch extends the existing startup APIs and
cmd functions to support shutdown instead of created new ones.

Prepare v2024.070-rc4

For pcr_read and pcr_extend commands allow the digest algorithm to be
specified by an additional argument. If not specified it will default to
SHA256 for backwards compatibility.

Additionally update test_tpm2.py for the changes in output in pcr_read
which now shows the algo and algo length in the output.

A follow-on to this could be to extend all PCR banks with the detected
algo when the <digest_algo> argument is 'auto'.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from all "cmd/" files and when needed add
missing include files directly.

For a TPM device to be operational we need to initialize it and
perform its startup sequence.  The 'tpm init' command currently calls
tpm_init() which ends up calling the ->open() per-device callback and
performs the initial hardware configuration as well as requesting
locality 0 for the caller.  There no code that currently calls
tpm_init() without following up with a tpm_startup() and tpm_self_test_full()
or tpm_continue_self_test().

So let's add a 'tpm autostart' command and call tpm_auto_start() which
leaves the device in an operational state.

It's worth noting that calling tpm_init() only, doesn't allow a someone
to use the TPM since the startup sequence is mandatory. We always
repeat the pattern of calling
- tpm_init()
- tpm_startup()
- tpm_self_test_full() or tpm_continue_self_test()
