platform/x86: ideapad-laptop: Add new _CFG bit numbers for future use 



Later IdeaPads report various things in last 8 bits of _CFG, at least
5 of them represent supported on-screen-displays. Add those bit numbers
to the enum, and use CFG_OSD_ as prefix of their names. Also expose
the values of these bits to debugfs, since they can be useful.
