We use the deprecated do_gettimeofday() function to read the current
time when resetting the statistics in both bfa_port and bfa_svc. This
works fine because overflow is handled correctly, but we want to get rid
of do_gettimeofday() and using a non-monotonic time suffers from
concurrent settimeofday calls and other problems.
This uses the ktime_get_seconds() function instead, which does what we
need here.

- Introduced support for D-Port which is a new port mode during which
link level diagnostics can be run.
- Provided mechanism to dynamically configure D-Port and initiate diagnostic
tests to isolate any link level issues.
- In D-Port mode, the HBA port does not participate in fabric or login to the
remote device or run data traffic.
- Diagnostic tests include running various loopback tests in conjunction with
the attached device.

- Modified the design such that each BFA sub-module will provide
the amount of DMA and KVA memory needed by it and queues the
same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
needed by all the BFA sub-modules as one contiguous chunk.

Introduced a generic event notification callback function that
receives IOC_ENABLED, IOC_DISABLED, IOC_FAILED events and notifies the
modules registered for these events.

We have flattened the BFA hierarchy and also reduced the number of
source and header files we used to have earlier.
