staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

If the "comedi" module has been loaded with the
"comedi_num_legacy_minors" module parameter set to a non-zero value,
some reserved comedi devices get created.  These can be attached to a
low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
which checks for the `CAP_SYS_ADMIN` capability.  Of course, the comedi
device needs to be opened before the ioctl command can be sent.  If the
comedi device is unattached, `comedi_open()` currently requires the
`CAP_NET_ADMIN` capability.  It makes more sense to just require the
`CAP_SYS_ADMIN` capability here, so change it.

For the curious, commit a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
when deciding to call request_module") changed this capability from
`CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
relevant here.  The original `CAP_SYS_MODULE` capability was due to the
function having some code to request a module using a "char-major-%i-%i"
alias, but that was never compiled in and was removed by commit
f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

staging: comedi: cb_pcimdas: add external analog output ranges

The analog output range is not programmable, but the ranges for each of
the two analog output channels are settable via jumpers.  These jumper
settings are not readable by the driver.  The driver
provides a range table containing all the possible internal ranges
(+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
application (although any range selected by the application that differs
from the jumper settings will not produce the expected voltage output).

The range table does not cover all possible ranges of the analog output
channels.  The jumpers also allow an external reference voltage between
0 and 10V to be used as bipolar or unipolar output range.  Add a couple
more ranges to the end of the range table to define these two external
ranges.
