Add the SAW (SPM), CPR-Hardened, CPUFREQ-HW nodes and relative OPP
tables (and also assign them to the CPU nodes, as required) in order
to enable CPU scaling on the MSM8998 SoC.
The CPR-Hardened and CPUFREQ-HW nodes are disabled by default as to
not change the previous default behavior. Since the drivers are not
yet accounting for speed-binning, these OPPs are referred to the
most common binning for this chip, which I have found on six phones
from Sony and one from FxTec (silver bin0, perf bin2).
At least until speed-binning gets done in the cpufreq-hw and CPR
drivers, users should enable CPR-Hardened and CPUFREQ in their own
board DT.
This is done like that because these drivers are really big, so the
idea is to keep the "base" version easier (but perfectly working),
before adding speed-binning "complications", which may... or may not
be necessary.
