Most Allwinner H5 boards start with VDD-CPUX at 1.1V (e.g. Orange Pi PC2,
NanoPi NEO2). Clocking it at 1008MHz is not so safe, and have shown
frequent CPU hang on my NanoPi NEO2 board.
Currently the ATF will also clock the system to 816MHz at boot.
So assign the default clock rate of H5 to 816MHz, as it's a more
reasonable and more safe value.
