Introduce a generic (*detach) function for comedi PCI drivers to handle
the boilerplate code needed to detach a PCI driver.
This function works similar to comedi_legacy_detach() where it will:
* free the dev->irq if it has been requested
* iounmap the dev->mmio addres if it has been ioremap'ed
The helper then calls comedi_pci_disable() to release the regions and
disable the PCI device.
Use the new helper directly for the (*detach) in the following cases:
* where comedi_pci_disable() is used directly for the (*detach)
* where the detach function is just boilerplate
Use the new helper in the (*detach) of the simpler PCI drivers. Call
the helper after disabling interrupts (reset) and before any additional
cleanup (kfree) to avoid any race conditions with the interrupt handler.
