The driver assumes that in 13bit mode the 16bit value has
to be shifted to the right by 3 bits. This is not true, in
both 16bit and 13bit mode the MSB is at the same position.
Currently the driver returns a temperature of 194 degrees
Celsius in 13bit mode and 24 degrees Celsius in 16bit mode.
Fix this by using the same algorithm for 16bit and 13bit
mode and by just masking out the lower three bits in 13bit
mode.

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded
IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise
the request will fail. This patch adds the IRQF_ONESHOT to IIO drivers where it
is missing.

The code expects the scan index to match the offset of the channel into the
channel array. For the "shorted" the offset is 3, but the scan index is set to
2. Also the scan index 2 is already taken by the previous channel. As a result
the "shorted" channel will appear to be selected if the previous channel is
selected and vice versa and it is not possible to sample the "shorted" channel
in buffered mode.

Use to_iio_trigger(dev) instead of dev_get_drvdata(dev). Both will return the

Use the new triggered buffer setup helper function to allocate and register
buffer and pollfunc.
The previous code was not passing the temperature channel to iio_buffer_register
since the temperature channel can not be used in buffered mode. With the new
helper functions it is not possible to do this, instead the scan index for the
temperature channel is set to -1 which will cause iio_buffer_register to ignore
the channel. (Also While we are at it also assign the symbolic constant instead
of the raw value to the channel address for the temperature channel).
