Comedi (*insn_write) functions are expected to write insn->n values to
the hardware. Fix this function to work like the core expects.
Also, use the comedi_offset_munge() helper to convert the comedi unsigned
values into the two's complement values that the hardware needs.

This member of the boardinfo for the NI MIO drivers is used to indicate if
the ranges for the analog output subdevice (ao_range_table in the boardinfo)
includes any unipolar ranges. If it's not set, the ao_range_table only has
bipolar ranges.
The 'ao_unipolar' flag is checked when munging the ao data values from the
user so that the values for bipolar ranges are converted to 2's complement
values before they are written to the hardware.
The flag is also used when programming the analog output configuration on
non-M series boards for bipolar/unipolar and external reference operation.
Simplify the driver a bit by removing this boardinfo flag and just using
the comedi_range_is_bipolar() and comedi_range_is_external() helpers to
check the range directly.

external source (RF_EXTERNAL).

During the attach of this driver, the digital output ports are all
initialized to a known state. Some of the boards supported by this
driver have output ports that are inverted from the comedi view of
the output state. For these boards the values written to the ports
needs to be inverted.
Currently, only bit 0 of each port is inverted when the boardinfo
indicates that the outputs are inverted. This results in channels
0, 8, 16, etc. being set to '0' and all other channels being set
to '1'. If the boardinfo does not indicate that the outputs are
inverted, all the channels are set to '0'.
This initialization is unnecessary for the input only ports. The
input/output ports also do not need to be initialized since they
are configured as inputs during the attach.
Move the output port initialization so it occurs when the digital
output subdevice is setup. Use the 's->io_bits' value to initialize
the ports so that the correct inverted/non-inverted state is used
for the comedi '0' value.

'invert_outputs'
Some of the boards supported by this driver have output ports that are
inverted from the comedi view of the output state. For these boards the
read values from the output ports needs to be inverted before being
modified and inverted again before being written back in the (*insn_bits)
operation.
Currently the subdevice type and the boardinfo is checked in the (*insn_bits)
to determine if the inverted outputs need to be handled.
Since thise driver does not use the subdevice 'io_bits', simplify the driver
a bit by initializing the 'io_bits' during the attach to handle the inversion.

Remove the need for the 'output_bits' in the private data by just
reading the current state of the data port when updating the output
channels in the (*insn_bits) function.
Add a local variable to handle the inverting of the hardware values
when the boardinfo indicates that the outputs are inverted.
Rename the local variable 'port_read_bits' to 'bits' so that we can
use it for updating the output channels and reading back the actual
state to return to the user.

There is only one member in the subdevice private data, an unsigned value
that is the 'base_port' that the subdevice uses to access the port registers.

Also in the latest silicon revision of AM335x, we do have a babble recovery

its better to have a rest_done return for musb_platform_reset().
