Dumping all the DDR takes significant time and there's currently no user-visible feedback provided to indicate that even the process has started. Solve this by wiring up the ux module and provide a progress bar while dumping segments, as well as information as the segments are skipped or dumped. Add missing ux_init() to the ramdump setup, and make sure to clamp value to max in the progress calculation, to avoid funky issues when progress is made beyond the size of the chunk.
