As more and more device-specific workarounds came up and gathered in various places, it becomes harder to manage. Now it's time to clean up and collect workarounds more consistently and make them more easily applicable.
This patch set introduces a new bitmap flags, quirk_flags, to contain various device-specific quirks. Those are separate one from the quirks in quirks-table.h; the quirks-table.h entries are for more intrusive stuff that needs the descriptor override, while the new quirk_flags is for easier ones that are tied with the vendor:product IDs.
