[PATCH v2] cpufreq: dt-platdev: allow RK3399 to have separate tunables per cluster

[Dmitry Torokhov]

RK3899 has one cluster with 4 small cores, and another one with 2 big
cores, with cores in different clusters having different OPPs and thus
needing separate set of tunables. Let's enable this via
"have_governor_per_policy" platform data.

v2 changes: commit message updated.

Not tested, but we had a patch unconditionally enabling
CPUFREQ_HAVE_GOVERNOR_PER_POLICY flag in tree we used to ship devices
based on RK3399 platform.
