Series crypto: sun8i-ce: add Allwinner H616 support | expand

The Allwinner H616 SoC contains a crypto engine very similar to the H6
version, but with all base addresses in the DMA descriptors shifted by
two bits. This requires a new compatible string.
Also the H616 CE relies on the internal osciallator for the TRNG
operation, so we need to reference this clock.
