ioctl, there are several options the user can supply that describe the
state of the hardware jumpers (LK1 for PCI224, LK1 thru LK5 for PCI234).
These options control how the driver sets up the AO range tables for the
device.  Those options are useless when the board is attached
automatically via the PCI driver probe function
`amplc_pci225_pci_probe()`, `comedi_pci_auto_config()`, and the
comedi driver "auto_attach" handler `pci224_auto_attach()`.

Rip out the range table selection options and use a single, static range
table per board type, containing all the software- and
hardware-selectable ranges for that board.  The PCI234 used to have a
per-channel `range_table_list` rather than an all-channel `range_table`,
as the jumpers selected different ranges for all channels.  Now that the
channels are using a unified range table, use an all-channel
`range_table` instead.

When checking the channel list for an asynchronous command in
`pci224_ao_check_chanlist()` make sure the ranges specified in the list
have compatible jumper settings.  We don't know how the jumpers are
actually set, but we can at least avoid conflicting settings.

Board types need to separate normal command like IO, MEM and so on.
And the board type will come after "board" string in config file normally.
(If it is not, dgap_gettok returns an error with zero)
After that, set a variable of a number which is matched with specific
a board number to "board.type". The dgap_gettok() returns that number so
just set to "board.type" and also "v_type" can be removed.

In case of boards of PCI type are set variables to zero. These can
be removed because "p" as cnode get memory from kzalloc so already
set to zero.
