clk: qcom: gcc: Set FORCE_MEM_CORE_ON for gcc_ufs_axi_clk for 8650/8750 



Update the force mem core bit for UFS 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 the UFS driver.
