Rex-BC Chen 0daa47325b cpufreq: mediatek: Link CCI device to CPU 
In some MediaTek SoCs, like MT8183, CPU and CCI share the same power
supplies. Cpufreq needs to check if CCI devfreq exists and wait until
CCI devfreq ready before scaling frequency.

Before CCI devfreq is ready, we record the voltage when booting to
kernel and use the max(cpu target voltage, booting voltage) to
prevent cpufreq adjust to the lower voltage which will cause the CCI
crash because of high frequency and low voltage.

- Add is_ccifreq_ready() to link CCI device to CPI, and CPU will start
  DVFS when CCI is ready.
- Add platform data for MT8183.
