ipq806x: fix uninitialized variable usage in cpufreq-krait
In krait_cpufreq_probe, both freq and max_cpu_freq are never
initialized, so the max_cpu_freq will have a random value at the end.
Fix this by properly initializing max_cpu_freq to 0 and storing the clk
frequency in freq as well, to make it similar to how it's calculated in
krait_set_target.
Fixes the following warnings:
