cpufreq: mediatek: Fix NULL pointer dereference in mediatek-cpufreq 

Fix following coccicheck error:
drivers/cpufreq/mediatek-cpufreq.c:464:16-23: ERROR: info is NULL but dereferenced.

Use pr_err instead of dev_err to avoid dereferring a NULL pointer.

Fixes: f52b16ba9fe4 ("cpufreq: mediatek: Use device print to show logs")
