[PATCH] media: ttpci: use rc-core for the IR receiver

[PATCH] media: ttpci: use rc-core for the IR receiver

[Sean Young]

The IR protocol can be set via the rc protocols sysfs file rather than
via module parameters and a custom procfs file. So, it is no longer
necessary to periodically check for protocol changes.

The IR_RCMM protocol does not match the Philips RC-MM protocol (12, 24 or
32 bit variants) so this is marked RC_PROTO_UNKNOWN for now. This protocol
not used by the remote for this device.

Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes
with a small black hauppauge remote.
