Matt Sealey 0d7d383098 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.
