[v3,00/27] staging: ccree: fixes and cleanups

The usual combo of code cleanups and fixes.

The highlights are:
- Use SPDX for all driver copyright/license
- Make ccree compliant with crypto API handling of backlog requests
- Make ccree compliant with Crypto API rules of resource alloc/release
- Settle on a single coherent file naming convention (which is why
  the diff looks so big)

Note that there are some fixes in the set that I currently consider
out of scope for stable. I will consider if I can/should roll
separate minimal fix patches for stable after these are taken.

With this set of changes, I've handled anything that I know about
that keeps it from moving out of staging to the best of my understanding
and would like to ask for a review before moving out of staging.

Changes from v2:
- Revert to SPDX-2.0 license tags as the kernel tools are not
  ready yet for 3.0

Changes from v1:
- Fixed wrong use of CPP style comments in SPDX include file
  headers as pointed out by Philippe Ombredanne.
- Moved to using SPDX-3.0 style GPL-2.0-only tags
- Rephrased one commit message to better clarify it is a fix
  and not just a cleanup
- Separated two commits which got squashed together unintentionally 
- Rebased on top of latest staging-next
