Running cpufreq-hw driver on Lenovo Yoga C630 laptop, the following
warning messages will be seen.
[ 3.415340] cpu cpu4: Voltage update failed freq=
2841600
[ 3.418755] cpu cpu4: failed to update OPP for freq=
2841600
[ 3.422949] cpu cpu4: Voltage update failed freq=
2956800
[ 3.427086] cpu cpu4: failed to update OPP for freq=
2956800
This is because the cpufreq-hw lookup table of SDM850 provides these two
set-points, but they are missing from OPP table in DT. Let's create
sdm850.dtsi to add the OPP for them, so that the warning will be gone.
