This is due to the following reasons, 1. Interfaces were incorrectly reporting as remote wakeup capable when host requested GET_STATUS. 2. Remote wakeup failures from DWC3 driver due to timeouts. Address them through this series. Changes in v2: - Don't advertise func wakeup capability if USB_CONFIG_ATT_WAKEUP is not set in bmAttributes. - Refactored func wakeup logic in linksts_change_interrupt().
