[U-Boot] [PATCH 2/3] ARM: iMX: define an IMX_CONFIG Kconfig option

[Boris Brezillon]

IMX_CONFIG is currently passed via the SYS_EXTRA_OPTIONS which is marked
as deprecated.

Add a new Kconfig file under arch/arm/imx-common and define the
IMX_CONFIG Kconfig in there.

Each board is supposed to provide a default value pointing to the
appropriate imximage.cfg file.
