u-boot-imx-tools: Rework the COMPATIBLE_MACHINE strategy

We need to avoid setting the COMPATIBLE_MACHINE when not using an i.MX
based machine, otherwise we end with multiple provides and cause
problems for outside machines.

To support both use-cases, and allow the use of u-boot-imx-tools, we set
the recipe as invalid for all use, except for 'use-mainline-bsp' and
'use-nxp-bsp' based machines.
