[PATCH v2 0/2] move TPM-specific fields into trusted_tpm_options

[Srish Srinivasan <ssrish@linux.ibm.com>]

The backend-agnostic trusted_key_options structure carries TPM-specific
fields. With the recent addition of a backend-private pointer, these fields
can be moved out of the generic options structure.

This patch series intends to reloacte all TPM-spcific fields into a newly
defined trusted_tpm_options structure. A pointer to the trusted_tpm_options
struct is stored in trusted_key_option's private.

Along with the migration of TPM-specific fields, this patch series includes
a preparatory clean-up patch: replacing pr_info() with pr_debug() and using
KERN_DEBUG for print_hex_dump() for logging debug information.

Testing covered both TPM 1.2 and TPM 2.0 backends (virtual environment),
including trusted key creation, revocation, unlinking, invalidation, and
loading keys from encrypted blobs. I would welcome any additional testing
from upstream to further strengthen the validation.

Changelog:

v2:
 * Exclude the bug-fix patch as it has already been applied to 6.19-rc7
 * Rename instances of trusted_tpm_options from tpm_opts to private
 * Use pr_debug and KERN_DEBUG for logging debug messages (preparatory
   clean up patch)
 * Address comments from Jarkko
