hdmirx: optimize audio fifo config [1/1]

Browse Source 
PD#SWPL-5579

Problem:
audio fifo underflow after switch audio pattern
on chroma 2233: only 2ch audio in, but audio fifo
is configed to read out 8ch afifo. chroma 2233
may change from multi-channel(witch audio overflows
and workaround to config read out all subpackets)
to 2-channel audio pattern, then issue happens.
so need to reset audio fifo config.

Solution:
except for workaround case, always config audio
fifo to only store valid subpackets.

Verify:
