commit ff712188daa3fe3ce7e11e530b4dca3826dae14a upstream.
When used on Huawei hisi platforms, Prolific Mass Storage Card Reader which the VID:PID is in 067b:2731 might fail to enumerate at boot time and doesn't work well with LPM enabled, combination quirks: USB_QUIRK_DELAY_INIT + USB_QUIRK_NO_LPM fixed the problems.
