HID: usbhid: Share USB device firmware node with child HID device

Browse Source 
USB HID core now shares its fwnode with its child HID device.
Since there can only be one HID device on a USB interface, it is redundant
to specify a hid node under the USB device. This allows usb HID device
drivers to be described in firmware and make use of device properties.
