Change history:
===============
v5(2022-05-17):
- Move opp tables to sun8i-r40-cpu-opp.dtsi
- cpufreq supports 720M, 912M, 1G, 1.1G, 1.2G
- Add cooling supports

v4(2022-05-16):
- Invert two patches.
- Drop the cpufreqs that exceeds 1G in opp tables.

v3:
- remove "allwinner-r40" compatible from allowlist.
- split dts in two part.

Test:
=====

cpufreq was tested by tools: https://github.com/ssvb/cpuburn-arm

1. cpufreq-ljt-stress-test

- root@ubuntu:~/cpuburn-arm-master# ./cpufreq-ljt-stress-test 
- CPU stress test, which is doing JPEG decoding by libjpeg-turbo
- at different cpufreq operating points.
