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.

Staging: ipack/bridges/tpci200: Clean up interrupt handling.

Previously the return value from tpci200_interrupt was not quite correct
if a slot had caused an interrupt but no handler was instellalled:
IRQ_NONE was returned.  However in this case we react to the interrupt
by disabling the IPack device interrupt.

Basically there are two cases the code now distinguishes:
 - The tpci200 has raised an interrupt.  We handle it and return
   IRQ_HANDLED.
 - Our device did not raise an interrupt. We return IRQ_NONE.

staging: comedi: icp_multi: use attach_pci callback

Convert this PCI driver to use the comedi PCI auto config attach
mechanism by adding an 'attach_pci' callback function. Since the
driver does not require any external configuration options, and
the legacy 'attach' callback is now optional, remove it. The
boardinfo is also not needed now so remove it also.

This also allows removing the icp_multi.h header completely.
