      ====================
      net: ipa: introduce ipa_syfs.c
      
      This series (its last patch, actually) creates a new source file,
      "ipa_syfs.c", to contain functions and data that expose to user
      space information known by the IPA driver via device attributes.
      
      The directory containing these files on supported systems is:
          /sys/devices/platform/soc@0/1e40000.ipa
      
      And within that direcftory, the following files and directories
      are added:
          .
          |-- feature
          |   |-- rx_offload          Type of checksum offload supported
          |   `-- tx_offload
          |   . . .
          |-- modem
          |   |-- rx_endpoint_id      IPA endpoint IDs for the embedded modem
          |   `-- tx_endpoint_id
          |   . . .
          |-- version                 IPA hardware version (informational)
              . . .
      
      The first patch just makes endpoint validation unconditional, as
      suggested by Leon Romanovsky.  The second just ensures the version
      defined in configuration data is valid, so the version attribute
      doesn't have to handle unrecognized version numbers.

      Add IPA device attributes to expose information known by the IPA
      driver about the hardware and its configuration.
      
      All pointers used to display these attribute values (i.e., IPA
      pointer and endpoint pointers) will have been initialized by the
      time IPA probe has completed, so they may be safely dereferenced.

      Define and use a new function that just validates the version
      defined in configuration data.
