clk: qcom: gcc-sc7280: Update force mem core bit for UFS ICE clock
[ Upstream commit f38467b5a920be1473710428a93c4e54b6f8a0c1 ]
Update the force mem core bit for UFS ICE clock to force the core on signal
to remain active during halt state of the clk. When retention bit of the
clock is set the memories of the subsystem will retain the logic across
power states.
