[media] ir-core: convert drivers/media/video/cx88 to ir-core
This patch converts the cx88 driver (for sampling hw) to use the decoders provided by ir-core instead of the separate ones provided by ir-functions (and gets rid of those). The value for MO_DDS_IO had a comment saying it corresponded to a 4kHz samplerate. That comment was unfortunately misleading. The actual samplerate was something like 3250Hz. The current value has been derived by analyzing the elapsed time between interrupts for different values (knowing that each interrupt corresponds to 32 samples). Thanks to Mariusz Bialonczyk <manio@skyboo.net> for testing my patches (about one a day for two weeks!) on actual hardware.
