Prevent platform profile error on unsupported systems

Browse Source 
If a system does not support setting the platform profile (i.e., does
not have the file /sys/firmware/acpi/platform_profile), then everything
that interacts with it is skipped to prevent errors. This situation is
more common than I expected.[1]
