staging:iio: Drop 4 meter drivers.

I announced an intent to drop all the meter drivers from staging as none of them have been the subject of substantial work in a very long time indeed.

For the ADE7854 John Syne stepped forward to say he had test hardware and Rodrigo Siqueira was keen to work on the cleanup. Some extensive conversations have been since had about the changes required in the IIO core to support these devices and the resulting userspace and kernel ABI that we need to get to for the drivers.

However, whilst this progress is excellent, the remaining four drivers are for obsolete and more or less unobtainable hardware. Hence I am now proposing we drop them. There are some great looking new meter parts out there from ADI (and I'm hopeful we'll be able to add support for some of those!), but they are very different devices.

I am going to take an increasingly hard look at the remaining IIO drivers in staging. Some have recieved considerable attention (quite a few have graduated in the last few months) so I'm happy with the progress on them. Others have sat there since before we took any of IIO out of staging and are not showing any signs of moving in the right direction.

Anyhow, if no one shouts in the next week I'll apply this series. Ideally I'd like some ack's on these, but appreciate that they are no longer really in anyone's purview.
