Older firmwares don't specify access flags for the controls, unfortunately the usage of some of these firmware relies on being able to read back values from the DSP. The current control code will only do this for volatile controls. This patch will read the control from the hardware if no flags are specified and the control is currently enabled, which should cover these legacy use-cases.
