The adis16448 is more or less from the same family of devices as supported by
this driver. It features three acceleration channels, three angular velocity
channels, three magnetometer channels, one temperature channels and one
barometric pressure channel.

Expose some information useful for debugging a device in debugfs. This includes
for now the flash count, the product id and the serial number and raw register
access.

The adis16400 and similar have two different base sampling rate available, from
which the actual sampling rate is derived. 1638 Hz and 52.85 Hz, switching to
the lower base sampling rate allows to support lower sampling rates.
This patch adds support for switching to the lower base sampling rate if the
requested sampling frequency is outside of the range which can be supported by
the higher base sampling rate.
The function which is used to read the current sampling rate already has support
for the lower sampling rate, so no changes are required there.

The devices supported by this drivers support sample rates with less than one
sample per second. To support this increase the samplerate precession to allow
setting (and reading) the samplerate with a milli-HZ precession.

This adis16400 driver is in pretty good shape now, so move it out of staging.

Smatch complains that snprintf() returns the number of characters,
not counting the NUL terminator, which *would* have been printed if
there were enough space. In other words the return value could be more
than sizeof(buf).
In this case, we are printing something like "ff.ff\n" which is at most
6 characters and a NUL so that's not an issue. I changed snprintf() to
scnprintf() to silence the warning.
But since the buffer doesn't include space for the NUL terminator, we
need to make it bigger or the "\n" will be truncated off.

Some of the newer generation devices from the ADIS16XXX series have more
registers than what can be supported with the current register addressing
scheme. These devices implement register paging to support a larger register
range. Each page is 128 registers large and the currently active page can be
selected via register 0x00 in each page. This patch implements transparent
paging inside the common adis library. The register read/write interface stays
the same and when a register is accessed the library automatically switches to
the correct page if it is not already selected. The page number is encoded in
the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

Now that the adis library no longer depends on the sw_ring buffer implementation
we can move it out of staging.
While we are at it also sort the entries in the iio Kconfig and Makefile to be
in alphabetical order.
