[PATCH v4 3/3] arm64: dts: qcom: Add INT2 GDSC to Kaanapali DPU

[Yongxing Mou <yongxing.mou@oss.qualcomm.com>]

The INT2 GDSC on Kaanapali (SM8850) powers the VIG2, VIG3 and DMA5
source pipes. Without enabling it, these pipes remain inaccessible.

The DPU is supplied by both CORE and INT2, so describe both GDSCs as
its power domains rather than attaching the DPU directly to their
parent MMCX domain.

Keep CORE attached to the parent MDSS device because it also supplies
shared MDSS hardware outside the DPU.
