[ Upstream commit ad2631b5645a1d0ca9bf6fecf71f77e3b0071ee5 ]
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.
