[media] ir-core: more cleanups of ir-functions.c
cx88 only depends on VIDEO_IR because it needs ir_extract_bits(). Move that function to ir-core.h and make it inline. Lots of drivers had dependencies on VIDEO_IR when they really wanted IR_CORE. The only remaining drivers to depend on VIDEO_IR are bt8xx and saa7134 (ir_rc5_timer_end is the only function exported by ir-functions). Rename VIDEO_IR -> IR_LEGACY to give a hint to anyone writing or converting drivers to IR_CORE that they do not want a dependency on IR_LEGACY.
