Known issues so far:

- le32/le64_to_cpu()'s and one cpu_to_le32 missing from tpm_crb.c
  assuming that CRB driver would be used in big-endian architecture.
- I still have troubles having FIFO testing environment so it would
  not be a big surprise if it had broke for some reason (help with
  testing and/or bug fixes for FIFO would be highly appreciated).

Notes about the implementation:

- Reworked the code base to the direction that Jason Gunthorpe suggested.
- Moved to use devres in tpm_crb as Jason suggested.
- Did some groundwork for implementing Stefan Bergers suggestions to
  tpm_crb.

I hope that it is now more in right direction than in my preview.

I'll push fixes on top of tpm2-v1 branch [1] and do not rebase it anymore
and therefore it is a good testing branch.

When things look good enough I'll create tpm2-v2 branch and prepare and
send a new patch set.
