Rob Herring (Arm) 5fdafebe57 arm64: dts: amlogic: Drop redundant CPU "clock-latency"
The "clock-latency" property is part of the deprecated opp-v1 binding
and is redundant if the opp-v2 table has equal or larger values in any
"clock-latency-ns". Add any missing "clock-latency-ns" properties and
remove "clock-latency".
