usb: core: hub: add quirk for hub with broken autosuspend function

Some USB host controller seems to have problems with
autosuspend. For example, Rockchip rk3328 SoC USB 3.0
wouldn't handle remote wakeup correctly with external
hub after entered autosuspend, caused to resume SS
port fail.

This patch introduces a new quirk flag for hub that
should remain disabled for autosuspend.
