comedi: Correct name of ACCES I/O Products

Commit 6cd5a9a35c3d ("staging/trivial: fix typos concerning "access"")
accidentally changed "Acces I/O Products" to "Access I/O Products",
although "Acces" should actually be a capitalized acronym "ACCES"
(standing for "Acquisition, Control, and Communication: Engineering &
Systems").  Change it in the "aio_aio12_8" and "aio_iiro_16" drivers and
change the Kconfig file to match.
