dt-bindings: clock: Document external clocks for MSM8998 gcc
The global clock controller on MSM8998 can consume a number of external
clocks. Document them.
For 7180 and 8150, the hardware always exists, so no clocks are truly
optional. Therefore, simplify the binding by removing the min/max
qualifiers to clocks. Also, fixup an example so that dt_binding_check
passes.
