====================
nfp: add NFP5000 support

This series broadly speaking adds support for NFP5000 and
related products.

First we add support for loading FW from flash.  We need to allow
for the management processor to provide extended log messages when
FW is loaded.  This is needed when FW selection policy is to compare
the FW on the disk and in the flash, and load the newer.  User should
be told what FW was selected.

We use this opportunity to add extended errors for normal FW loading
as well.

Next we add support for requesting HW information from the management
processor.  Up until now the driver read the HWinfo as it appears in
card memory, but there can be cases when management processor has
additional information or generates the entries dynamically so
occasionally we will have to consult it.  We use this to look up MAC
addresses for PCIe netdevs.

Next the actual patch with NFP5000 support and a small dose of
refactoring of PCIe init.

The remaining patches add support for reading RTsymbol types we
didn't need before.  Ones explicitly placed in external memory unit's
cache and absolute ones.

This part begins with a patch moving the logic which figures out
the correct bit offsets to device probe, to avoid redoing the
calculation for each access.  Second patch adds error messages
for easier troubleshooting.  Next patch adds helpers which will
take care of address conversions to reach into EMU cache.
Subsequently users are migrated from the raw CPP API to the new RTsym
helpers.  Finally we add support for reading absolute symbols.
