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.

Changes since v1:
- Fixed USB product id and product name
- Disabled some other options to free more space
- Changes now passed CI tests: https://dev.azure.com/u-boot/u-boot/_build/results?buildId=1492&view=res...
Note that this patch depends on other Nokia RX-51 patches which are on mailing list, otherwise CI tests do not pass:

okay, Ill wait for all these patches to get merged, before I pick this patch.
Web pages for all these patches is saying:
State: Under Review Delegated to: Lokesh Vutla
So I think these patches are also waiting for you.
Thanks and regards, Lokesh
