clk: qcom: cpu-8996: fix the init clock rate

Current multiplier (60) results in CPU getting the rate which is
unlisted in the CPU frequency tables (60 * 19.2 = 1152 MHz). This
results in warnings from the cpufreq during startup.

Change PLL programming (l = 54) to init CPU clocks to start with the
frequency of 54 * 19.2 = 1036.8 MHz which is supported by both power and
performance clusters from all speed bins.
