Subject: [PATCH v2 09/17] arm: dts: qcom: ipq4019: 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". The OPP table has values of 256000, so it can be
removed.
