The current enpoint logic ignores all bulk endpoints and uses
a fixed mapping between endpint addresses and the supported
data stream types (analog/audio/DVB):
Ep 0x82, isoc => analog
Ep 0x83, isoc => audio
Ep 0x84, isoc => DVB
Now that the code can also do bulk transfers, the endpoint
logic has to be extended to also consider bulk endpoints.
The new logic preserves backwards compatibility and reflects
the endpoint configurations we have seen so far:
Ep 0x82, isoc => analog
Ep 0x82, bulk => analog
Ep 0x83, isoc* => audio
Ep 0x84, isoc => digital
Ep 0x84, bulk => analog or digital**
(*: audio should always be isoc)
(**: analog, if ep 0x82 is isoc, otherwise digital)

By disabling the NEC parity check, it is possible to handle all 3 NEC
protocol variants (32, 24 or 16 bits).
Change the driver in order to handle all of them.
Unfortunately, em2860/em2863 provide only 16 bits for the IR scancode,
even when NEC parity is disabled. So, this change should affect only
em2874 and newer devices, with provides up to 32 bits for the scancode.
Tested with one NEC-16, one NEC-24 and one RC5 IR.
