The "comedi_fc" module contains a few functions useful to Comedi
drivers. Their functionality is being migrated to the core "comedi"
module and renamed to start with the prefix `comedi_`. As part of this
migration, move `cfc_write_array_to_buffer()` into the core comedi
module and rename it to `comedi_write_array_to_buffer()`. Change the
external declaration of `cfc_write_array_to_buffer()` into an inline
function that calls `comedi_write_array_to_buffer()`.
