staging: comedi: 8255_pci: fix namespace due to rename of driver

Due to the rename of this file, change all the adl_pci7296_* to
pci_8255_* so that everything has namespace associated with this
driver.

Also, fix the comedi description comment based on the rename of
the file. Remove the extra comment about the driver attach.

Modify the PCI_DEVICE_ID_* defines in preparation of moving
additional vendor/device ids into this driver.

-Status: testing
-
-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.
-
-These boards also have an 8254 programmable timer/counter chip.
-This chip is not currently supported by this driver.
