ACPI: thinkpad-acpi: Remove firmware backlight delays for Intel ACPI IGD OpRegion
Based on analysis and a patch from Matthew Garrett <mjg59@srcf.ucam.org>.
Instruct the ThinkPad ACPI firmware to remove delays on the processing of
backlight brightness changes. This method is present on ThinkPad
Vista-compatible BIOSes with standard ACPI backlight level control.
