The "GMU Wrapper" is Qualcomm's name for "let's treat the GPU blocks we'd normally assign to the GMU as if they were a part of the GMU, even though they are not". It's a (good) software representation of the GMU_CX and GMU_GX register spaces within the GPUSS that helps us programatically treat these de-facto GMU-less parts in a way that's very similar to their GMU-equipped cousins, massively saving up on code duplication. The "wrapper" register space was specifically designed to mimic the layout of a real GMU, though it rather obviously does not have the M3 core et al. GMU wrapper-equipped A6xx GPUs require clocks and clock-names to be specified under the GPU node, just like their older cousins. Account for that.
