Subject: [PATCH v4 0/3] Add Support for Cavium Cryptographic Acceleration Unit

This series adds the support for Cavium Cryptographic Accelerarion Unit (CPT) 
CPT is available in Cavium's Octeon-Tx SoC series.                            
                                                                              
The series was tested with ecryptfs and dm-crypt for in kernel cryptographic
offload operations. This driver needs a firmware to work, I will be sending the
firmware to linux-firmware once the driver is accepted.

Changes v3 -> v4
	--Addressed Corentin Labbe's coments
		- Convert all pr_x to dev_x.
		- Fix Typo errors.
		- Fix the Double unlock.
		- Use sg_virt.
Changes v2 -> v3
	-- Addressed David Daney's comments
		- There is not much difference in performance readq/writeq vs 
	readq_relaxed/writeq_relaxed, so switching to readq/writeq variant.
		- Removed the useless bitfield definitions.
		- Use GENMASK,dev_to_node() instead of custome functions.
		- Use module_pci_driver instead of module_init/exit.
Changes v1 -> v2                                                              
	-- Addressed a crash issue when more gather components are passed.
        -- Redo the cptvf request manager.                                    
   	     - Get rid of the un necessary buffer copies.                  
        -- s/uint*_t/u*                                                
        -- Remove unwanted Macro definitions                           
        -- Remove the redundant ROUNDUP* macros and use kernel function
        -- Select proper config option in Kconfig file.                
        -- Removed some of the unwanted header file inclusions                
        -- Miscellaneous Cleanup
