staging: comedi: ni_mio_common: fix subdevice flags for PFI subdevice
[ Upstream commit e083926b3e269d4064825dcf2ad50c636fddf8cf ]
The PFI subdevice flags indicate that the subdevice is readable and
writeable, but that is only true for the supported "M-series" boards,
not the older "E-series" boards. Only set the SDF_READABLE and
SDF_WRITABLE subdevice flags for the M-series boards. These two flags
are mainly for informational purposes.
