HACK: clk: qcom: mmcc-8996: Tie MMAGIC_BIMC_GDSC to the MMAGIC GDSCs of multimedia blocks
The MMAGIC_BIMC_GDSC is required to fetch from the memory. Without enabling
this, we end up seeing a blue screen on display.
Set MMAGIC BIMC GDSC as the parent for all the MMAGIC GDSCs of all the
multimedia blocks. This isn't the ideal solution since there isn't a real
parent-child relationship between the GDSCs. The BIMC GDSC should ideally
be tied to the power domain of a device that manages the noc/bus clocks.
Until we have device using this power domain, stick to this method.
