efikamx: refine USB support
Because of the way USB pad settings are handled it doesn't make sense to be able to build the Efika MX board support without CONFIG_CMD_USB turned on. So, we change the build to always compile in USB support. We do not need to check for CONFIG_CMD_USB like we do with CONFIG_MXC_SPI since the USB subsystem will error out of the compile for us. Additionally, the following behaviors have changed; * Smartbook "preboot" should not set input and output to USB keyboard as there is no display support * board_eth_init is implemented such that it does not cause U-Boot to report an explicit failure ("CPU Net Initialization Failed"). Since Ethernet is implemented via USB (fixed on Smarttop, pluggable on Smartbook, and handled by "usb start") - the warning that is left ("No ethernet found") is perfectly reasonable at the point it is printed since the USB system hasn't been started and nothing has been probed yet.
