Subject: [PATCH 01/10] arm64: dts: mt8183: Fix Mali GPU clock

From: Chen-Yu Tsai <wenst@chromium.org>

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.
