clk: qcom: gpucc-sm6350: Introduce index-based clk lookup
[ 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.
