Hi Hans,
Jeremy Cline correctly points out in rhbz#1514836 that a device where the QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship with a different wifi/bt chipset in some configurations.
If that is the case then we are needlessly penalizing those other chipsets with a reset-resume quirk, typically causing 0.4W extra power use because this disables runtime-pm.
This commit moves the DMI table check to a btusb_check_needs_reset_resume() helper (so that we can easily also call it for other chipsets) and calls this new helper only for QCA_ROME chipsets for now.
