V4L/DVB: Convert drivers/media/dvb/ttpci/budget-ci.c to use ir-core 

Converts drivers/media/dvb/ttpci/budget-ci.c to use ir-core rather than
rolling its own keydown timeout handler and reporting keys via
drivers/media/IR/ir-functions.c.

[mchehab@redhat.com: Drop the call to ir_input_init() as it is no longer needed]
