Now when usbtty serial console is fixed in U-Boot enable CONFIG_USB_TTY for Nokia RX-51 board by default.
Fix also USB product id as U-Boot ignores CONFIG_USBD_PRODUCTID macro and include U-Boot string into USB product name to indicate usage of U-Boot. CONFIG_CONSOLE_MUX is already used and U-Boot console is available for all in/out devices. Therefore there is no need to have separate commands 'run sercon', 'run usbcon' and 'run vgacon', so remove them. As space for U-Boot is limited to 256kB, disable some other unused options so CONFIG_USB_TTY can be enabled. Nokia RX-51 does not have easily accessible UART serial console so the only option for easy debugging is to use device's keyboard+screen or this usbtty serial console over USB.
