Merge branch 'qed-File-split-and-rename-towards-iWARP-support'

Michal Kalderon says:

====================
qed*: File split and rename towards iWARP support

This patch series makes a few more infrastructure changes towards adding
iWARP support. Hopefully this is the last infrastructure change
prior to the iWARP RFC.

Patch #1-3 take care of taking all the common iWARP/RoCE code out of
qed_roce.[ch] and placing it in qed_rdma.[ch]
Patch #4 renames the roce interface file as it is common for
RoCE and iWARP. This patch touches qedr as well.
====================
