====================
net: ipa: start adding IPA v5.0 functionality

The biggest change for IPA v5.0 is that it supports more than 32
endpoints.  However there are two other unrelated changes:
  - The STATS_TETHERING memory region is not required
  - Filter tables no longer support a "global" filter

Beyond this, refactoring some code makes supporting more than 32
endpoints (in an upcoming series) easier.  So this series includes
a few other changes (not in this order):
  - The maximum endpoint ID in use is determined during config
  - Loops over all endpoints only involve those in use
  - Endpoints IDs and their directions are checked for validity
    differently to simplify comparison against the maximum
