[PATCH v2 0/5] Add support for SM3 secure hash

[Heiko Schocher]

Add SM3 secure hash, as specified by OSCCA GM/T 0004-2012 SM3 and described
at https://datatracker.ietf.org/doc/html/draft-sca-cfrg-sm3-02

TPMv2 defines hash algo sm3_256, which is currently
not supported and prevented TPMv2 chip with newer
firmware to work with U-Boot. Seen this on a ST33TPHF2XI2C

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

Implement sm3 hash, so we can fix this problem.

Changes in v2:
rebase to
6b27b688694: ("Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sh")
add Ilias to Series-cc
add sm3_hash to header file, so we can use it.
add comments from Ilias
- use ARRAY_SIZE(hash_algo_list) instead of a fix number
  in tpm2_get_pcr_info() for the count of supported hashes
  in U-Boot.
- add SM3 hash in tpm_tcg2
