[PATCH v2 10/10] sandbox: tpm: Support extending a PCR multiple times

[Simon Glass]

It is fairly easy to handle this case and it makes the emulator more
useful, since PCRs are commonly extended several times.

Add support for this, using U-Boot's sha256 support.

For now sandbox only supports a single PCR, but that is enough for the
tests that currently exist.

Changes in v2:
- Drop the constant sandbox_extended_once_pcr since we can calculate it
- Update the commit message to explain that there is only one PCR
