Subject: [PATCH v2] cpufreq: cpu0: drop selecting of THERMAL and THERMAL_CPU

From: Rob Herring <robh@...nel.org>

The addition of THERMAL and THERMAL_CPU selections causes a kconfig
warning on highbank platforms:

warning: (ARM_HIGHBANK_CPUFREQ) selects GENERIC_CPUFREQ_CPU0 which has
unmet direct dependencies (ARCH_HAS_CPUFREQ && CPU_FREQ && HAVE_CLK &&
 REGULATOR && OF && THERMAL && CPU_THERMAL)

The cpufreq-cpu0 driver does not require thermal zone support to
function as highbank does not need these, so drop selecting of THERMAL
and CPU_THERMAL.

v2:
- just drop selecting THERMAL and THERMAL_CPU instead of a new kconfig
  option

Dropping REGULATOR doesn't build w/o some empty regulator functions, so
that's 3.15 material.
