Subject: [PATCH v2 0/3] Fixes for USB3 CV Chapter 9.15 tests

While performing USB3 Command Verifier Chapter 9 tests, failures
were observed during 9.15 ("Function Remote Wakeup Enabled Test").
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().

Prashanth K (3):
  usb: gadget: f_ecm: Add get_status callback
  usb: gadget: Use get_status callback to set remote wakeup capability
  usb: dwc3: gadget: Make gadget_wakeup asynchronous
