staging: iio: meter: Drop ade7854 driver

This driver is so far from making correct use of the IIO infrastructure
and ABI that if someone wanted to make the driver suitable for moving
out of staging, they would more or less be starting from scratch.

As such there is little point in keeping the existing code in staging.

Note this was only user of the meter.h header so that is dropped.
There are no other drivers in the staging/iio/meter directory so drop
the build system files as well.

staging: iio: Drop ADIS16060 driver from staging

This part has been declared "not for new designs". It is now
difficult to obtain and we have had no-one come forward with hardware
making it difficult to proceed with the necessary work to move this
driver out of staging.

The device uses two separate chip selects and would require locking
between them which is thought to be difficult to enforce without
non trivial changes in the SPI subsystem. This work simply isn't worth
doing given the status of the part and the fact no one seems to have
gone for a similar hardware design since this one.

If anyone does have access to one of these and is willing to contribute
the time necessary then we can reevaluate dropping the driver.

hwmon: Move the IIO client driver for hwmon out of staging

This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client

IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

The only non move changes here concern the description and changes to the
dependencies to IIO explicit and hwmon implicit.

I'm proposing moving this into hwmon on the basis of placing drivers
based on what they provide rather than what their underlying hardware
is.

staging:iio: drop sw_ring buffer implementation.

Whilst this is IIO's oldest buffer implementation it is messy, poorly
implemented and whilst it works, no one is entirely sure it always will.

New IIO drivers have not been using this for some time and now all remaining
old users have been converted to use the kfifo based alternative.

Clearly a fifo isn't the same as a ring buffer but in many use cases it
really doesn't matter. We also loose the watershed based poll implementation.
However having poll effectively report data only when the buffer was half
full was at best an 'unusual' use of the interface.

At somepoint in the future we may bring watersheds back on a different
buffer implementation, but then we will think a lot more about how to do
the interface first.
