Merge branch 'ipa-sysfs'

Alex Elder says:

====================
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.
