Note that some registers should not be read since firmware is already reading them. If driver reads those, they will be cleared-on-read, and so the firmware stats will be incorrect. For these 'do-not-read' stats, add them to the registers definition so that other developers can be aware of these constraints, but do not actually read them in the driver.
