The Anbernic RG35XX device variants (-2024, -H, -Plus and -SP) are the
only currently known devices to have an Allwinner H700 SoC. The closely
related RG28XX also has the H700 but a mainline DT for this device has
not yet been submitted.

Include the H616 CPU OPP table in the base device DTS, and increase the
DCDC1 regulator (vdd-cpu) upper voltage range to 1.16V, allowing the
CPU to reach 1.5GHz.
