Most calls to cx231xx_capture_start() already use the values from
TRANSFER_TYPE, but cx231xx_capture_start() and
cx231xx_initialize_stream_xfer() were hand coding the values.
Use the named values (81 is never passed in), and simplify
cx231xx_capture_start(), as the switch statements were identical and
pcb_config->config_num is a u8, so any non-zero config got the same
result.

This may not be strictly necessary for audio to work, and has only been
tested on my HVR-850 (2040:b140). I don't know if there are devices out
there that break if we enter HANC.
