Enable equivalent function on a v5 CCP. Add support for a
version 5 CCP which enables AES/XTS/SHA services. Also,
more work on the data structures to virtualize
functionality.

The CCP has the ability to provide DMA services to the
kernel using pass-through mode of the device. Register
these services as general purpose DMA channels.
Changes since v2:
- Add a Signed-off-by
Changes since v1:
- Allocate memory for a string in ccp_dmaengine_register
- Ensure register/unregister calls are properly ordered
- Verified all changed files are listed in the diffstat
- Undo some superfluous changes
- Added a cc:

Support for different generations of the coprocessor
requires that an abstraction layer be implemented for
interacting with the hardware. This patch splits out
version-specific functions to a separate file and populates
the version structure (acting as a driver) with function
pointers.
