staging: comedi: remove 'comedi_autoconfig' module parameter

This module parameter is used to enable the auto config mechanism
in the comedi core. Most of the PCI, PCMCIA, and USB drivers have
been converted to use the auto config mechanism and will not attach
if it is disabled.

Since the 'comedi_autoconfig' parameter is defaulted to true, just
remove it so that the comedi drivers that use auto config will
always be able to attach.

 Status: untested
 
-This driver only attaches using the PCI PnP auto config support
-in the comedi core. The module parameter 'comedi_autoconfig'
-must be 1 (default) to enable this feature. The COMEDI_DEVCONFIG
-ioctl, used by the comedi_config utility, is not supported by
-this driver.
-
 The PCI-7230, PCI-7432 and PCI-7433 boards also support external
 interrupt signals on digital input channels 0 and 1. The PCI-7233
 has dual-interrupt sources for change-of-state (COS) on any 16
 digital input channels of LSB and for COS on any 16 digital input
 lines of MSB. Interrupts are not currently supported by this
 driver.
