cpufreq: update to sysfs_emit() for safer buffer handling

Browse source

Replace sprintf() and scnprintf() with sysfs_emit() and sysfs_emit_at()
in the cpufreq core.

This ensures safer buffer handling and consistency with sysfs interfaces.

Update show_scaling_available_governors() and related functions for
compliance with the new API.
