The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.
So lets move the whole folder out of staging.

The AD5662 is compatible to the AD5660, but uses an external
reference instead of an internal.

The devices supported by this drivers only have a single shift register, which
contains both the power down mode and the output sample. So writing the power
down mode and the output sample can be done by the same function. Call this
function prepare_write as it will prepare the spi message for a write. Also
introduce a small helper function which performs the whole write by calling the
chip the specific prepare function followed by a spi_sync.
The two power down bits are always placed ontop of the msb of the output sample,
so we can easily calculate their position by adding the channels shift to the
channels realbits.

There are three identical chip_info entries. Remove two of them and use the id
of the remaining entry for all three device table entries.

We currently only write 16 bit in case where we should write 24 bit. The spi message
length is calculated from the channel storage_size, but since the storage size
is only 16 bit we end up with the wrong value for devices which have power down
bits and thus a register with 24 bit. Since each store function knows how many
bytes it has to write just use the spi_write function from there instead of
going through the hassle of manually preparing a spi_message and keeping buffers
in the state struct.
Another advantage of this patch is that it will make implementing support for
similar I2C based DACs much easier.
