arm64: dts: allwinner: h616: Add CPU OPPs table

Browse source

Add an Operating Performance Points table for the CPU cores to enable
Dynamic Voltage & Frequency Scaling (DVFS) on the H616.
The values were taken from the BSP sources. There is a separate OPP set
seen on some H700 devices, but they didn't really work out in testing, so
they are not included for now.

Also add the needed cpu_speed_grade nvmem cell and the cooling cells
properties, to enable passive cooling.
