media: amphion: Add a frame flush mode for decoder

Browse source

By default the amphion decoder will pre-parse 3 frames before starting
to decode the first frame. Alternatively, a block of flush padding data
can be appended to the frame, which will ensure that the decoder can
start decoding immediately after parsing the flush padding data, thus
potentially reducing decoding latency.

This mode was previously only enabled, when the display delay was set to
0. Allow the user to manually toggle the use of that mode via a module
parameter called low_latency, which enables the mode without
changing the display order.
