On systems that allow CPUs to run at an extremely reduced frequency, it is possible to create an "interrupt" storm by USB settings that are not ideal at these speeds. This patch series introduces a quirk bit that currently only touches the Interrupt Control register but might be used in the future with other similar registers. This change allows for firmware (or scripts) to set these registers as required in place of using hard-coded values which might not be ideal for all platforms.
