arm: nxp: k6x: Add default partition table.

Browse source 
Recent changes (69255043, 91f67a13, 84628e8b, fa4a3932) add support
for a partition table in the flash.  Add support for this to the nxp
k6x dtsi file.  By default, code will occupy the entire flash.  By
setting a chosen node in an application, the code can be linked into
one of the partitions.  For example, and app could create a
'frdm_k64f.overlay' file at the top of their project with:

    / {
        chosen {
            zephyr,code-partition = &slot0_partition;
        };
    };

to place an application in slot 0.
