iwlwifi: mvm: Support version 3 of tlc_update_notif.

As part of the new rate_n_flags, a new version of tlc_update_notif
was added in FW in order to support the new rate_n_flags.
Add support for the new version, and move the all API to use the
new rate_n_flags only (if FW supports the old one - convert it).
