Minor change from previous version (change PCE for 3.0 layout).

Subject: [PATCH 1/3] avcodec/aacenc: Fixes in PCE table
The LFE layouts were previously replaced by SCE due to bad ordering.
This was actually a problem with the aac native decoder not the encoder.
The commit reinstates LFE channels for layouts using them.
The 3.0 PCE has also been changed for better support by the native decoder.
(some style fixes also)
