Take the core support + the kfifo buffer implentation out of
staging. Whilst we are far from done in improving this subsystem
it is now at a stage where the userspae interfaces (provided by
the core) can be considered stable.
Drivers will follow over a longer time scale.

There is one device supported by the driver which is not listed in the Kconfig
help test. This patch adds it. Also we are past the point were we can possible
fit all devices supported by the driver in the Kconfig entry title, so just list
the initial device that was supported by this driver and note that similar
devices are supported as well.

We can not read back the value from the device, but we cache the value anyway so

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.

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.

Both the powerdown mode bits and the sample value are stored in the same
register, so writing a sample while the device is powered down will clear the
power down bits. To avoid this only update the cached value when the device is
powered down.

v1 actually had a small bug in that it would still write to the device's
register when the sample was updated while the device was powered down. This was
not critical since it would send out the powerdown mode again.

s626_attach is referencing s626_pci_table which is annotated
__devinitconst. Put pci vendor/device ids in the s626_board struct and
use s626_boards instead similar to what is done in gsc_hpdi.
v2: I had moved the PCI id defines to s626.h earlier, but later
decided to leave them in s626.c and forgot to move them up above where
they are being used in s626_boards.

Move the module_init/module_exit routines and the associated
struct comedi_driver variable to the end of the source. This is
more typical of how other drivers are written and removes the
need for the forward declarations.
Also, move the do_config function to remove needing to have
a forward declaration for that routine.
