clk: qcom: gcc-x1e80100: Set FORCE MEM CORE for UFS clocks
[ Upstream commit 201bf08ba9e26eeb0a96ba3fd5c026f531b31aed ]
Update the force mem core bit for UFS ICE clock and UFS PHY AXI clock to
force the core on signal to remain active during halt state of the clk.
If force mem core bit of the clock is not set, the memories of the
subsystem will not retain the logic across power states. This is
required for the MCQ feature of UFS.
