ARM: dts: msm: add boost frequency for cpufreq and devfreq for msm8996pro

Update the cpufreq device with the boost frequency for the CPU
power cluster as well as the characterized Turbo Fmax frequency
and new intermediate Turbo frequency for the performance cluster
on speed bin 0 parts.  Lastly, update the cpufreq to devfreq
device frequency mapping so that it includes all of the new CPU
cluster frequencies.
