Current code assumes that both host and device operates in Little Endian
in lots of places. While this is true for x86 platform, this doesn't mean
we should not care about this.

This commit addresses all parts of the code that were pointed out by sparse
checker. All operations with restricted (__be*/__le*) types are now
protected with explicit from/to CPU conversions, even if they're noops on
common setups.

I'm sure there are more such places, but this implies a deeper code

LL2 queues were a limited resource due to FW constraints.
This FW introduced a new resource which is a context based ll2 queue
(memory on host). The additional ll2 queues are required for RDMA SRIOV.
The code refers to the previous ll2 queues as ram-based or legacy, and the
new queues as ctx-based.
This change decreased the "legacy" ram-based queues therefore the first ll2
queue used for iWARP was converted to the ctx-based ll2 queue.
This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation
which didn't have an effect in other use cases.

There are several wide-bus registers written to by the fw_funcs
that require using the dmae for atomicity. Therefore using the dmae
channel functionality was added to the fw_funcs file, since the code
is very similar to the previously used code, the structures used were
moved to qed_hsi. Due to FW conventions, the names of the flags in the
struct changed. Since this required slight modification in the places
that set the flags the code was modified to use GET/SET FIELD macros.

This patch refactors the current llh implementation. It exposes a hw
resource called ppfid (port-pfid) and implements an API for configuring
the resource. Default configuration which was used until now limited
the number of filters per PF and did not support engine affinity per
protocol. The new API enables allocating more filter rules per PF and
enables affinitizing protocol packets to a certain engine which
enables full 100g protocol offload support.

Currently driver registers to physical link notifications (of the device)
from Management firmware (MFW). Driver doesn't get notified if there's a
change in the virtual link e.g., link-flap on the peer PF interface.
Virtual link indication from MFW reflects the per PF link status instead
of the physical link.

The patch adds driver support for,
  - Advertising the virtual link support to MFW.
  - Handling the virtual link notification from MFW.
