arm64: dts: allwinner: h6: Enable CPU opp tables for Beelink GS1
Enable CPU opp tables for Beelink GS1. This needs to change the CPU regulator max voltage to fit the OPP table. Also add the ramp-delay information to avoid any out of spec running as the regulator is slower at reaching the voltage requested compare to the PLL reaching the frequency. There is no such information for AXP805 but similar PMIC (AXP813) has a DVM (Dynamic Voltage scaling Management) ramp rate equal to 2500uV/us.
