Fix HID gadget device remote wakeup issue

Enable Bit(6): Self-powered & Bit(5): Remote Wakeup
to allow host users to decide whether HID gadget device
can wakeup host or not.
Host Controller would set REMOTE_WAKEUP feature before
suspend, and the devices acked accordingly.

Tested: Host can be waked up by HID device when KVM client
is connected.

OpenBMC IpKVM Server

The obmc-ikvm application is a VNC server that provides access to the host graphics output. The application interfaces with the video device on the BMC that captures the host graphics, and then serves that video data on the RFB (remote framebuffer, also known as VNC) protocol. The application also interfaces with the BMC USB gadget device to pass HID events from the BMC to the host, allowing the user to interact with the host system.

Usage

Once the host is running and an appropriate HID gadget device is instantiated on the BMC, the application can be started with the following command: obmc-ikvm -v <video device path> -i <HID gadget device path>

For example:

obmc-ikvm -v /dev/video0 -i /dev/hidg0
