Add PLL clock support for the main CCU of the Allwinner A733 SoC. The structure is mostly similar to the sun55i, with the addition of a PLL_REF clock that normalizes the hardware-detected DCXO/hosc frequency (19.2MHz, 24MHz, or 26MHz) into a consistent 24MHz reference for all subsequent PLLs. The behaviors of PLL_AUDIO0 and PLL_AUDIO1 are ported from the vendor driver. Specifically, PLL_AUDIO0 is configured with SDM parameters to provide a 22.5792MHz * 4 output, while PLL_AUDIO1 is integrated into the main CCU without using SDM.
