DVDVideoCodecAmlogic: Remove throttling of MPEG2 playback

* 56ebbc6 introduced logic in place for playback conditions on the Amlogic
  devices. However, after this commit was merged MPEG2 streams started to
  be HW decoded and thus throwing off the logic put in place to accomodate
  direct .VOB playback.
* Remove the MPEG2 width check and let amcodec handle the playback if all
  else checks out

[AE] Allow resampler to indicate when it has too much data buffered

The Pi resampler doesn't want more samples submitted when it has a whole input buffer queued,
and drops data in this case. This can be triggered when video clock is enabled and audio is resampled.

The FFMPEG resampler buffers more data internally and wants up to two input buffers submitted.

Add a method to query if there is space for more samples, and return approprate values.
