Subject: [PATCH v2] arm64: dts: qcom: msm8996: Move UFS_GDSC to UFS HCD

The UFS_GDSC backs the resources needed by the UFS HCD, rather than the
PHY. This results in the UFS HCD occationally failing to enable some of
its clocks.

Move the UFS_GDSC reference to the UFS HCD node instead, to correct
this.

Signed-off-by: Bjorn Andersson <bjorn.andersson@...aro.org>

Changes since v1:
- Dropped UFS_GDSC from phy node
