[media] nuvoton-cir: improve buffer parsing responsiveness

Browse Source 
Rather than waiting for trigger bits, the formula for which was slightly
messy, and apparently, not actually 100% complete for some remotes, just
call ir_raw_event_handle whenever we finish parsing a chunk of data from
the rx fifo, similar to mceusb, as well as whenever we see an 'end of
signal data' 0x80 packet.
