ENGR00230538-5: CAAM: Add SM register defs

Add SM register defs, and expanded driver-private storage.

These add changes to the driver private areas for the CAAM
controller and CAAM Secure Memory subsystems, and expand register
definitions to include the Secure Memory subsystems as reflected
in multiple areas (controller, rings, secure memory itself).
