staging: comedi: amplc_pc236: remove manual configuration of PCI boards

Browse source 
Remove the code that allows PCI boards to be manually attached by the
`COMEDI_DEVCONFIG` ioctl (or the "comedi_config" application).
Supported PCI boards (PCI236) will be attached automatically at probe
time via `comedi_pci_auto_config()` and the `auto_attach` hook in the
`struct comedi_driver`.

The "wildcard" entry in `pc236_boards[]` was only used when manually
attaching a PCI board using a driver name instead of a board name, so is
no longer needed.  Remove it.

* Driver: amplc_pc236
* Description: Amplicon PC36AT, PCI236
* Author: Ian Abbott <abbotti@mev.co.uk>
* Devices: [Amplicon] PC36AT (pc36at), PCI236 (pci236 or amplc_pc236)
* Updated: Wed, 01 Apr 2009 15:41:25 +0100
* Devices: [Amplicon] PC36AT (pc36at), PCI236 (pci236)
* Updated: Thu, 24 Jul 2014 14:25:26 +0000
* Status: works
*
* Configuration options - PC36AT:
* [0] - I/O port base address
* [1] - IRQ (optional)
*
* Configuration options - PCI236:
* [0] - PCI bus of device (optional)
* [1] - PCI slot of device (optional)
* If bus/slot is not specified, the first available PCI device will be
* used.
* Manual configuration of PCI board (PCI236) is not supported; it is
* configured automatically.
*
* The PC36AT ISA board and PCI236 PCI board have a single 8255 appearing
* as subdevice 0.
