[PATCH 1/3] tpm: update tpm hash algorithm according to tpm2.0 spec 1.59

[Benjamin BARATTE]

The hash algorithm structure shall reflect the TCG specification for
TPM2.0
With vesion 1.59, the SHA3 algorithm has been added and shall be
reflected in this structure.
The fact that U-Boot does or does not support SHA3 algo yet is not
relevant for this structure.
It's up to the end user to configure the active PCR bank to supported
hash algorithm by all boot chain component.
Also, by default, TPM2.0 shall support at least SHA256 and SHA384, in
practice dTPM support 2 actives banks with this 2 hash algorithms
