HID: uhid: add UHID_CREATE and UHID_DESTROY events
UHID_CREATE and UHID_DESTROY are used to create and destroy a device on an
open uhid char-device. Internally, we allocate and register an HID device
with the HID core and immediately start the device. From now on events may
be received or sent to the device.
The UHID_CREATE event has a payload similar to the data used by
Bluetooth-HIDP when creating a new connection.
