Subject: [PATCH net-next 00/11] net: ipa: memory region rework, part 1

This is the first portion of a very long series of patches that has
been split in two.  Once these patches are accepted, I'll post the
remaining patches.

The combined series reworks the way memory regions are defined in
the configuration data, and in the process solidifies code that
ensures configurations are valid.

In this portion (part 1), most of the focus is on improving
validation of code.  This validation is now done unconditionally
(something I promised Leon Romanovsky I would work on).  Validation
will occur earlier than before, catching configuration problems as
early as possible and permitting the rest of the driver to avoid
needing to do some error checking.  There will now be checks to
ensure all defined regions are supported by the hardware, that
required regions are all defined, and that there are no duplicate
regions.

The second portion (part 2) is mainly a set of small but pervasive
changes whose result is to have the memory region array not be
indexed by region ID.  I'll provide further explanation when I post
that series.
