So we have two issues with the non-standard devicetree use
for omap clocks:
1. Multiple clock nodes with the same reg property
This we sorted out for the clkctrl binding, but we still
have other clocks with this issue.
I guess some of them can be now removed if they are just
legacy clkctrl clocks.
For the rest we could maybe group them under a node with
just one reg property?
The clocks could just look up the reg property from parent
in this case.
2. Dependency to using custom clock node names
This can be sorted out by adding custom compatibles to
the parent node for both clkctrl clock manger nodes and
for the clocks grouped in step #1 above I think.

With steps #1 and #2 above I think this issue would
also disappear, the clock framework naming could be like
what we already use for the clkctrl clocks.
