arm64: dts: sdm850: Add OPP tables for 2.84 and 2.96GHz 

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.
