When attaching a PCI224 or PCI234 manually via the `COMEDI_DEVCONFIG`

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.

incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some

https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.
