media: dvb: Seperate secure demuxing to secure feeds only
In current implementation secure demux performs demuxing on all filters
including non-secure filters.
This implementation fails in case output buffer is externally allocated by
the user from a heap that does not allocate physically contiguous memory,
which is allowed for non-secure filters.
Secure filters buffers are guranteed to be allocated from a heap that
allocates physically contiguous memory.
To overcome this problem, this patch splits the processing between
normal sw demux filters, and secure demux filters.
Filters which user defined as secured will be processed only by the secure
demux, while other filters will be processed by the normal sw demux.
