The actual clock feeding into the Mali GPU on the MT8183 is from the clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN block, which itself is simply a pass-through placeholder for the MFGPLL in the APMIXEDSYS block. Fix the hardware description with the correct clock reference.
