staging: iio: ad5933: change help rule message
Remove the previous comment about direct access via sysfs which would
lead one think ad5933 driver has limitations it actually doesn't.

staging: add missing SPDX lines to Kconfig files
There are a few remaining drivers/staging/*/Kconfig files that do not
have SPDX identifiers in them. Add the correct GPL-2.0 identifier to
them to make scanning tools happy.

staging:iio:impedance-analyzer switch from sw_ring to kfifo.
sw_ring buffer implementation is going away so switch to the
kfifo based alternative.

Functionality is generic, so name is missleading.

staging: iio: Move sensor drivers to sub menus
We have a lot of drivers now, so the iio sub menu becomes quite large.
This patch creates sub menus for the different sensors.

iio: impedance-analyzer: New driver for AD5933/4 Impedance Converter, Network Analyzer
The AD5933 is a high precision impedance converter system solution
that combines an on-board frequency generator with a 12-bit, 1 MSPS,
analog-to-digital converter (ADC). The frequency generator allows an
external complex impedance to be excited with a known frequency.
The response signal from the impedance is sampled by the on-board ADC
and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine.
The DFT algorithm returns a real (R) and imaginary (I) data-word at each
output frequency.
Changes since V1:
Apply list review feedback:
Consistently use poll_time_jiffies.
Use be|le cpu endian helpers where applicable.
Add various comments.
Changes since V2:
Fix KernelVersion tag in Documentation.
Declare ad5933_default_pdata static.
Fix typos.
