Subject: [PATCH 03/11] arm64: dts: qcom: lemans: Add power-domain and iface
 clk for ice node

Qualcomm in-line crypto engine (ICE) platform driver specifies and votes
for it's own resources. Before accessing ICE hardware, the 'core' and
'iface' clocks must 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 'core' and 'iface' clocks in the ICE node for lemans.
