plugins/hwprofile: adapt to the new plugin arguments scheme

Browse source 
Parsing boolean arguments correctly (e.g. pattern=on or source=false).
Introduced a new "track" argument that takes a [read|write] value. This
substitutes passing read or write to "arg=" that is deprecated.

Also, matches are now taken one by one through the "match" argument.
