Currently the TPM driver allows other kernel subsystems to read only the
SHA1 PCR bank. This patch modifies the parameters of tpm_pcr_read() and
tpm2_pcr_read() to pass a tpm_digest structure, which contains the desired
hash algorithm. Also, since commit 125a22105410 ("tpm: React correctly to
RC_TESTING from TPM 2.0 self tests") removed the call to tpm2_pcr_read(),
the new parameter is expected to be always not NULL.

Due to the API change, IMA functions have been modified.

Does not apply to the current upstream (with tpm1-cmd.c).
