The recent cleanups have decimated the drivers code size by quite a bit. It is
only a few hundred lines in total now. Putting everything into one file also
allows to reduce the code size a bit more by removing a few lines of boilerplate
code. The only functional change made by this patch is that we now always
include buffer support, instead of making it optional. This is more consistent
with what we do for other drivers.

The temperature scale and offset depend on the reference voltage, the current
formula used in the driver assumes a 2.5V reference. This patch modifies the
code to report the unprocessed value for the temperature channel "raw" property
and to provide proper "scale" and "offset" properties which depend on the
selected reference voltage.

Rework the regulator handling of the driver to match more closely what we do in

Also dispose the option of specifying the reference voltage via platform data.

For buffered mode we do not want to perform endianness conversion in the kernel,
but rather offload it to user space, since it is not always required to do a
conversion at all. It also greatly simplifies the kernel code since no
post-processing has to be done and may allow future optimizations like streaming
data directly to a storage device or over the network via DMA.

Currently the driver reads out all sample registers of the device and throws
away those which it does not need. Furthermore the SPI message is constructed
each time the trigger handler is run, although it will be the same each time.
This patch preallocates and pre-constructs the SPI message in the
"update_scan_mode" callback. Only those register which are actually selected for
sampling are included in the message. The patch also gets rid of the conversion
of the sample data from big endian to the native endianness and instead marks
the channel as big endian in its scan type. This allows to directly push the
SPI transfer buffer to the IIO buffer without the need to post-process it.

Use the triggered buffer helper functions to setup and tear down the buffer for

A lot of the devices from the ADIS family use the same methods for accessing
registers, sampling data and trigger handling. They also have similar register
layout for the control registers.
This patch adds a common library for these devices. The library implements
functions for reading and writing registers as buffer and trigger management. It
also provides a set functions for accessing the control registers and for
running the devices internal self-test. Having this common library code will
allow us to remove a lot of duplicated code.

We had assigned the return value to 'ret' but ignored it when
return from isl29018_write_raw(), it's better to return 'ret'
instead of 0.

The function is expected to return the number of bytes consumed and as long as
not all bytes have been consumed the function will be called again. Currently
the function returns 'ret', which will always be 0 in this case, so we end up in
a endless loop since the caller will assume that no bytes have been consumed. So
instead return len as it is supposed to.
