[PATCH] cpufreq: kyro: Reduce frame-size of qcom_cpufreq_kryo_probe()

[Viresh Kumar]

With the introduction of commit 846a415bf440 ("arm64: default NR_CPUS to
256"), we have started getting following compilation warning:

qcom-cpufreq-kryo.c:168:1: warning: the frame size of 2160 bytes is larger than 
2048 bytes [-Wframe-larger-than=]

Fix that by dynamically allocating opp_tables and freeing it later.

Compile tested only.
