By using the info_mask_shared_by_all element of the channel spec, acce
to the sampling frequency becomes available to in kernel users of the
driver. It also shortens and simplifies the code.
This particular conversion was made more complicated by the shared library
and the fact that a number of the drivers do not actually have support for
setting or reading the sampling frequency. The hardware, in those cases
investigated supports it. It's just never been implemented.

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.

Some of the newer generation devices from the ADIS16XXX family have 32bit wide
register which spans two 16bit wide registers. This patch adds support for
reading and writing a 32bit wide register.

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.
