6.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit f6f89d194e4ddcfe197ac8a05ed4161f642a5c68 ]
Add the nowadays-prefered and marginally faster way of looking up parent clocks in the device tree. It also allows for clock-names-independent operation, so long as the order (which is enforced by schema) is kept.
