====================
qed: QM & ILT changes

This series introduces several changes and improvements to existing
queue manager and ILT configurations done during initialization.
Notice some of the patches are actually future fixes, I.e., bugs that
can't be triggered with exisiting driver but are needed for some future
functionality.

Patch #1 refactors the configuration of the hardware's queue manager,
which is quite messy today. This contains most of the bulk [code-wise]
in the series.

Patch #2, #3 fix Timers related ILT configurations that are yet to
affect qed in existing scenarios.

Patch #4 reduces needless ILT lines wasted for RoCE configurations.

Patch #5 allows RoCE partitions to manage with less memory regions
[important, e.g., for Multi-function parititions with RoCE support].
