[PATCH 2/9] tpm: Avoid code bloat when not using EFI_TCG2_PROTOCOL

[Simon Glass]

It does not make sense to enable all SHA algorithms unless they are
needed. It bloats the code and in this case, causes chromebook_link to
fail to build.

Add a condition to TPM to correct this. Note that the original commit
combines refactoring and new features, which makes it hard to see what
is going on.

Fixes: 97707f12fda tpm: Support boot measurements
