imx-base.inc: Allow for setting different IMX_DEFAULT_BSP values

Current assignment of the IMX_DEFAULT_BSP variables is too strong. For
example, any IMX_DEFAULT_BSP value set in local.conf currently gets
overridden by the assingment in imx-base.inc. Soften the assignment
to allow for alternative values for these variables.
