This results in clearing the capabilities structures, in order to set them up for operating in safe mode, ensuring many features are disabled. This has a side effect of also clearing the capability bits that relate to NVM update. The result is that the device driver will not indicate support for unified update, even if the firmware is capable. Fix this by adding the relevant capability fields to the list of values we preserve. To simplify the code, use a common_cap structure instead of a handful of local variables. To reduce some duplication of the capability name, introduce a couple of macros used to restore the capabilities values from the cached copy.
