DSPManager: WM8994 big cleanup

 - Refactored and removed a lot of unneeded code.
 - Remove global enabling preference as it isn't useful and breaks
   our feature detection mechanism.
 - Use voodoo_sound instead of wm8994_sound to restore compatiblity
   with Voodoo Sound app. (need kernel change)
 - Disable control when Voodoo Sound app is installed to prevent
   conflict.

Update equalizer for channel independence

Previously, I simply summed channel power values together when
calculating the loudness correction estimation. Now loudness is
adjusted per ear. This is unfortunately bit of a hack because
headset filtering can now mix the coloration intended for one ear
to another, but on the other hand the problem is limited by the
relative similarity of the chosen boosts for nearly all music there
is. I will probably fix the problem by moving loudness compensation
into the headset filtering code later.

Also treble boost was corrected slightly to reduce excess brightness.

Improve headsetfilter's primitive space simulation

Instead of making the left and right ear ping-pong exactly same
length, choosing a couple of close prime values causes a more
complicated ping-pong echo pattern which seems more natural.

Improve Finnish translations

Some things were awkwardly worded ("Aseta Esiasetettu" =
technically "Set Preset" but nobody speaks that way).

Description of loudness compensation was not specific enough
("Äänen kompensointi" = "Sound compensation"). Corrected to
sound level compensation.

Some terms were not logical opposites, such as "tehostus"
("increase of power") and "alennus" ("decrease of level").
Switched to "korostus" and "vaimennus" which are often used
in Finnish literature, and mean emphasis/de-emphasis.

Selected passive "Käytössä" ("In use") over the active,
"Aseta" ("Set") for effect master toggles. We should change
English's Enable -> Enabled, imho.

Translated Equalizer and Bass boost effect names.

Capitalization issues fixed.

Slight DSPManager parameter tuning

Increase Haas effect slightly for "stage", extra wide feeling.
Disable reverb properly for "studio".
