The ccree driver is now in the cryptodev tree, so remove it from
drivers/staging as it's no longer needed here.
Based on a patch from Gilad, but the mailing list didn't like it :(

Fix a wrong offset used in splitting a 64 DMA address to MSB/LSB
parts needed for scatter/gather HW descriptors causing operations
relying on them to fail on 64 bit platforms.

With all users removed or re-factored to use the standard
kernel bit fields ops we can now drop the custom
bit field macros.

A bunch of macros used to define M/LLI descriptors where
being defined in the C file. Move them over to private
include file where other relevant definitions are stored.

The Linked List Item descriptors were being programmed via
a set of macros which suffer a few problems:
- Use of macros rather than inline leaves out parameter type
checking and risks multiple macro parameter evaluation side
effects.
- Implemented via hand rolled versions of bitfield operations.
This patch refactors LLI programming into a set of
of inline functions using generic kernel bitfield access
infrastructure, thus resolving the above issues and opening
the way later on to drop the hand rolled bitfield macros
once additional users are dropped in later patches in the
series.

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.
