Up until now the call to initialize the USB subsystem was hardcoded for U-Boot running as an EFI payload. This was used to enable the use of a USB keyboard in the U-Boot shell. However not all boards might need this functionality. As initializing the USB subsystem can take a considerable amount of time (several seconds on some boards), we now initialize the USB subsystem only if U-Boot is configured to use USB keyboards.
