That makes it incompatible to the H6 variant, and thus requires a new compatible string. Clock wise it relies on the internal oscillator for the TRNG, so needs all four possible clocks specified. Add the compatible string to the list of recognised names, and add the H616 to list of devices requiring all four clocks.

To accommodate the larger address space, the CE task descriptor fields holding addresses are now encoded as "word addresses", so take the actual address divided by four. This is true for the fields within the descriptor, but also for the descriptor base address, in the CE_TDA register. Wrap all accesses to those fields in a function, which will do the required division if needed. For now this in unused, so there should be no change in behaviour.

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.
