msm: cpufreq: Check cpufreq_frequency_table NULL
This is required during single kernel binary support where one target
supports cpufreq and other target is at the initial stages of bringup.
Since we cannot remove CONFIG_CPU_FREQ_MSM from the config file, but
still support the boot on both of them adding a check for targets where
table is not initialized by the acpu clock driver.
