arm64: dts: qcom: sdm670: add frequency profile

Add the coefficients for the CPU frequencies to aid in frequency
scaling.

Profiling setup:
 - freqbench (https://github.com/kdrag0n/freqbench)
 - LineageOS kernel, android_kernel_google_msm-4.9
 - recommended configuration options by freqbench
 - disabled options that require clang or 32-bit compilers
 - mmc governor switched from simple_ondemand to powersave

    Frequency domains: cpu1 cpu6
    Offline CPUs: cpu1 cpu2 cpu3 cpu4 cpu5 cpu6 cpu7
    Sampling power every 1000 ms
    Baseline power usage: 445 mW
