Please Note This patchset has not been tested yet on any Hardware platform.
i could only confirm there's no compile error. :)
I test previous single patch on the Yamaha A/V receiver which works well, the
test results was also confirmed by some guys from XBMC forum.

The idea of this patch comes from Anssi, Big credit to him at first!

Any comments are appreciated!

* do not touch channel_allocation priority order, use new api to get
correct channels number
* use spdif->status to check audio type, pcm or non-pcm 
* create new non_pcm_mapping[] for non_pcm audio in seperate block
* add non_pcm hdmi_spec_per_cvt to remember previous audio type, used to 
  determine whether need a channel mapping update during the pcm/non-pcm 
  stream switch with same channel number.
