The "amplc_pci224" driver retains a "legacy" attach mechanism via the
`COMEDI_DEVCONFIG` ioctl and the comedi driver "attach" hook, but
usually attaches PCI devices automatically via the comedi driver's
"auto_attach" hook. The legacy mechanism is only retained so that
options can be passed via the ioctl to indicate how some hardware
jumpers are set on the boards, which is used to set up the range tables.
That's no use if the PCI device is attached automatically as the range
tables will be set up according to the factory default jumper positions.
Change the range tables to include all possible ranges, regardless of
jumper positions. Then there is no need to have options to control
setting up the range tables and the "legacy" attach mechanism can be
removed.
Also, tidy the code up a bit.
