Merge patch series "Add support for SM3 secure hash"

Browse Source 
Heiko Schocher <hs@nabladev.com> says:

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.
