drivers: clk: qcom: ipq5424: fix the freq table of sdcc1_apps clock
The divider values in the sdcc1_apps frequency table were incorrectly updated, assuming the frequency of gpll2_out_main to be 1152MHz. However, the frequency of the gpll2_out_main clock is actually 576MHz (gpll2/2). Due to these incorrect divider values, the sdcc1_apps clock is running at half of the expected frequency. Fixing the frequency table of sdcc1_apps allows the sdcc1_apps clock to run according to the frequency plan.
