Cory Maccarrone c2fd1a4ebf HID: Add the GYR4101US USB ID to hid-gyration
This change adds in the USB product ID for the Gyration
GYR4101US USB media center remote control.  This remote
is similar enough to the other two devices that this driver
can be used without any other changes to get full support
for the remote.
