qcacmn: Add optional wifi datapath feature ipa layer

This change adds the optional wifi datapath feature
to transfer data to and from modem via WLAN.
By using the existing path between WLAN and IPA, this
change registers new interfaces between IPA and WLAN
to reserve, add, delete and release rx filters,
which are required for setting up CCE filter rules.
These filters help to determine which packets need
to be routed to IPA specific REO rings.
