Since the commit b4e13e1ae95e ("scsi: ufs: qcom: Add multiple frequency support for MAX_CORE_CLK_1US_CYCLES") the Qualcomm UFS driver uses core_clk_unipro values from frequency table to calculate cycles_in_1us. The DT file for MSM8996 passed 0 HZ frequencies there, resulting in broken UFS support on that platform. Fix the corresponding clock values in the frequency table.
