This (*insn_read) function was used to read 16-bit analog input data
from the boardACL8216 boardtypes. The 12/16-bit differences are now
handled by the pcl812_ai_eoc() and pcl812_ai_get_sample() helpers.
Remove this function and use pcl812_ai_insn_read() for all boardtypes.

Some of the boards supported by this driver can do differential analog
input when configureg with jumpers on the board. When diff. ai is used
the number of input channels is half the single-ended number of channels.
The user specifies the analog input mode for these boards when attaching
to the driver by using a configuration option.
Remove the unnecessary 'n_aichan_diff' member from the boardinfo. Add a
comment for the boards that can do differential ai.
Refactor pcl812_attach() to parse the user option before setting up the
subdevices. We can then use the 'use_diff' flag to determine if the ai
is single-ended or differential and set the subdev_flags and n_chan.

We do:
if (NOB > DEFAULT_BUFF_SIZE)
BuffSize = DEFAULT_BUFF_SIZE;
else
BuffSize = NOB;
Since NOB can be negative it results in a larger than intended BuffSize
and makes kzalloc() fail.
The code is still a bit crap because it lets the users read as much as
they want from nvram, but I don't know what a sensible upper limit
should be.

File cfg80211.c is included by p80211netdev.c, p80211netdev.c includes
<net/cfg80211.h>, both ieee80211_channel_to_frequency() and
IEEE80211_BAND_2GHZ is defined / declared in <net/cfg80211.h>. So this
change is safe.
This change is a preparation for the removal of function
