[PATCH] dt-bindings: iio: ti,ads8688 yaml conversion

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Fairly simple binding.  Most of the changes were filling in information
not previously found in the binding.  I dropped the previous explicit
mention of spi-max-frequency as that is covered by the generic SPI
binding.

Sean, are you fine with being explicitly listed at the maintainer
of this binding?  Previously we didn't have that formally laid
out in the old txt bindings but it's now a required field.

I'm going to slowly work my way through some of the simpler yaml conversions
over the next few months.   Of course I welcome anyone else taking
some of these on but for purposes of review, please keep it to only
a few at a time.
