Series clk: mediatek: mt8183: Fix GPU/MFG clock rate changing | expand

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.
