[PATCH 5/5] arm64: dts: qcom: sc8280xp: Add OPP table for CCI hosts

[Konrad Dybcio <konradybcio@kernel.org>]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

The CCI hosts have both frequency and voltage requirements (which
happen to be common across instances on a given SoC, at least so far).

Express them by introducing an OPP table and linking it to the hosts.
