MT8173 is a ARMv8 based SoC with 2 clusters. All CPUs in a single cluster
share the same power and clock domain. This series tries to add cpufreq support
for MT8173 SoC.

Changes in v4:
- Add bindings for MT8173 cpufreq driver
- Move OPP table back into device tree
- Address comments for last version

Changes in v3:
- Implement MT8173 specific standalone cpufreq driver instead of using
  cpufreq-dt driver
- Define OPP table in the driver source code until new OPP binding is ready

Changes in v2:
- Add intermediate frequency support in cpufreq-dt driver
- Use voltage scaling code of cpufreq-dt for little cluster instead of
  implementaion in notifier of mtk-cpufreq driver
- Code refinement for mtk-cpufreq driver
