This device has separate events for a sort of decaying average and for
the raw value. We don't have a way of specifying this as yet.
For now I have both resulting in the same event code.

I won't guarantee I got these right, but they are certainly closer than
the abuse of buffer event codes that was perviously in here.

Use iio channel spec for the ring buffer channels.
Add/update file comment/license headers.
Use available_scan_masks to prevent that multiple channels are enabled.
Remove wavefrom type attributes. (no handled directly by the scan_elements)
Use SPI_MODE_1.
Move ade7758_initial_setup() before ade7758_probe_trigger() to ensure the
ADE7758 interrupt is disabled when the host interrupt get's enabled.
Add spi_device_id.
Update ring buffer setup.
Some backporting needed to ensure driver builds all the way through core

These should have been merged a long time ago, but there we are.
V3: rebase fixup + add missing extend_name for supply on adis16350
V2: Move to single IIO_CHAN macro + use the new extend_name
to make the naming of the temperature sensors contain x, y, z
rather than messing with modifiers. This a very weird case
and I don't want temperature to use axial modifiers.
