* Added support for translating the SGLs associated with incoming

* Mpt3sas driver uses the NVMe Encapsulated Request message to

* The controller firmware sends separate events for NVMe devices and
PCIe switches similar to existing SAS events.
* NVMe device detection, addition and removal are reported by the
firmware through PCIe Topology Change list events.
* The PCIe device state change events are sent when the firmware
Sets nvme device queue depth, name and displays device capabilities.

Currently we allocate 3 sets of DMA memories from separate
pools for each slot. This is inefficient in terms of memory usage
(buffers are less than 1 page in size, so we lose due to alignment),
and also time spent in doing 3 allocations + de-allocations per slot,
instead of 1.
dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by work with const
dev_pm_ops. So mark the non-const structs as const.
