thinkpad_acpi: Don't yell on unsupported brightness interfaces
The thinkpad_acpi driver currently emits error messages on unsupported brightness interfaces, giving the impression that someone will implement those. However, this error is spit out on nearly every thinkpad in production since 2 years now. Furthermore, the backlight interfaces on those devices are supported by the i915 driver just fine. Downgrade the error message to a normal pr_info() and stop telling people to report it to IBM.
