Adjust hash length such that it will not be fixed and general for all algs.
Instead make it suitable for certain context information.
This is preparation for SM3 support.

Add support for Arm TrustZone CryptoCell 713.
Note that this patch just enables using a 713 in backwards compatible mode
to 712. Newer 713 specific features will follow.

Use managed clock handling, differentiate between no clock (possibly OK)
and clock init failure (never OK) and correctly handle clock detection
being deferred.

The product signature and HW revision register have different offset on the
older HW revisions.
This fixes the problem of the driver failing sanity check on silicon
despite working on the FPGA emulation systems.

Introduce basic low level Arm TrustZone CryptoCell HW support.
This first patch doesn't actually register any Crypto API
transformations, these will follow up in the next patch.
This first revision supports the CC 712 REE component.
