i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
During initialization, depending on the device id, the template members
are initialized with function pointers specific to the ppc or
xscale controllers.

i. Register 16 byte CDB capability with scsi midlayer
"Ths patch properly registers the 16 byte command length capability of the
megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
hardware supports 16 byte CDB's."

i. New template defined to represent each family of controllers (identified by processor used).
The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

i. Code reorganized to remove code duplication in megasas_build_cmd.
"There's a lot of duplicate code megasas_build_cmd. Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"
- Christoph Hellwig <hch@lst.de>
ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
"MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"
