Find 7a: Use audio configs from find7op stock firmware

derived from the 1+1 system dump

-- speakers are louder
-- Wired Headsets do work

Removed PCM offload as our frameworks and HAL don't support it yet - it causes
horrible audioflinger crashes if turned on here.

Also disabled PCM flags in voip_rx in audio_policy as that's another item which
we don't have proper framework support for yet.  In its current state it causes
the HAL to try and open an output stream that's already open when Maps tries to
issue voice prompts.

PS5: incall volume fixed, reduced speaker volume a bit
