PM / devfreq: Replace strncpy with strscpy
GCC produces this warning when kernel compiled using `make W=1`:
warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation]
772 | strncpy(devfreq->governor_name, governor_name, DEVFREQ_NAME_LEN);
The strncpy doesn't take care of NULL-termination of the destination
buffer, while the strscpy does.
