dt-bindings: clock: ti: Convert autoidle binding to yaml
Autoidle clock is not an individual clock; it is always a derivate of some
basic clock like a gate, divider, or fixed-factor. This binding will be
referred in ti,divider-clock.yaml, and ti,fixed-factor-clock.yaml.
As all clocks don't support the autoidle feature e.g.,
in DRA77xx/AM57xx[1], dpll_abe_x2* and dpll_per_x2 don't have
autoidle, remove required properties from the binding.
Add the creator of the original binding as a maintainer.
