dt-bindings: clock: fix rk3399 cru clock issues

The current rk3399 cru DT node gives warnings like:
'clocks' is a dependency of 'assigned-clocks'.

With the YAML conversion somehow "assigned-xxx" properties where added.
If a proper clock is added to the cru node these properties are no longer
needed, so removed them. Currently only one clock will be added, so limit
the clock maxItems to 1. Add a clock name to be able to differentiate
and filter bogus entries.

dt-bindings: clock: use generic node name for pmucru example in rockchip,rk3399-cru.yaml

The node names should be generic, so fix this for the pmucru node example
in the rockchip,rk3399-cru.yaml file and rename it to "clock-controller".

dt-bindings: clock: replace a maintainer for rockchip,rk3399-cru.yaml

With the rk3399 cru YAML conversion the original text author was
somehow added as a maintainer, but who's currently no longer involved
on the subject. Replace this position with the Rockchip clock maintainer
on her request.

dt-bindings: clock: fix some conversion style issues for rockchip,rk3399-cru.yaml

With the conversion of rockchip,rk3399-cru.txt a table with external clocks
was copied. Make it a bit cleaner by aligning the columns. Also fix
a description. Phrases start with a capital.
