arm64: dts: allwinner: h616: add additional CPU OPPs for the H700

Browse Source 
The H700 now shows stable operation with the 1.008, 1.032 and 1.512 GHz
DVFS operating points. The 1.5GHz OPP requires a VDD-CPU of 1.16V,
obtained from the vendor BSP. This voltage is slightly above the
recommended operating voltage for the H616 (H700 datasheet not publicly
available) but well within the absolute maximum of 1.3V.

Add the additional 1.032 GHz operating point to the H616 CPU-OPP table,
and enable the 1.008 and 1.512 points for the H700.
