[PATCH v2 09/11] arm64: dts: qcom: sm8650: Add power-domain and iface clk for ice node

Qualcomm in-line crypto engine (ICE) platform driver specifies and votes
for its own resources. Before accessing ICE hardware during probe, to
avoid potential unclocked register access issues (when clk_ignore_unused
is not passed on the kernel command line), in addition to the 'core' clock
the 'iface' clock should also be turned on by the driver. This can only be
done if the UFS_PHY_GDSC power domain is enabled. Specify both the
UFS_PHY_GDSC power domain and the 'iface' clock in the ICE node for sm8650.
