Add support for TEE based trusted keys where TEE provides the functionality
to seal and unseal trusted keys using hardware unique key. Also, this is
an alternative in case platform doesn't possess a TPM device.

This patch-set has been tested with OP-TEE based early TA which is already
merged in upstream [1].

[1] https://github.com/OP-TEE/optee_os/commit/f86ab8e7e0de869dfa25ca05a37ee070d7e5b86b

Changes in v8:
1. Added static calls support instead of indirect calls.
2. Documented trusted keys source module parameter.
3. Refined patch #1 commit message discription.
4. Addressed misc. comments on patch #2.
5. Added myself as Trusted Keys co-maintainer instead.
6. Rebased to latest tpmdd master.

Changes in v7:
1. Added a trusted.source module parameter in order to enforce user's
   choice in case a particular platform posses both TPM and TEE.
2. Refine commit description for patch #1.

Changes in v6:

Changes in v5:
1. Drop dynamic detection of trust source and use compile time flags
   instead.
2. Rename trusted_common.c -> trusted_core.c.
3. Rename callback: cleanup() -> exit().
4. Drop "tk" acronym.
5. Other misc. comments.
6. Added review tags for patch #3 and #4.

Changes in v4:
1. Pushed independent TEE features separately:
  - Part of recent TEE PR: https://lkml.org/lkml/2020/5/4/1062
2. Updated trusted-encrypted doc with TEE as a new trust source.
3. Rebased onto latest tpmdd/master.

Changes in v3:
1. Update patch #2 to support registration of multiple kernel pages.
2. Incoporate dependency patch #4 in this patch-set:
   https://patchwork.kernel.org/patch/11091435/

Changes in v2:
1. Add reviewed-by tags for patch #1 and #2.
2. Incorporate comments from Jens for patch #3.
3. Switch to use generic trusted keys framework.
