imx: ventana: make hwconfig initialize based on board configuration
The hwconfig env var allows user to control hardware specific configuration of board specific features but not all Ventana boards have the same features. We will use the magic default value of "_UNKNOWN_" to signify that the bootloader should create this based on detected board model. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
