tools/imximage: share DCD information via Kconfig

Browse source 
IMX based platforms can have the DCD table located on different
addresses due to differences in their memory maps (ie iMX7ULP).

This information is required by the user to sign the images for secure
boot so continue making it accessible via mkimage.

Indicates where the Device Configuration Data, a binary table used by
the ROM code to configure the device at early boot stage, is located.
This information is shared with the user via mkimage -l just so the
image can be signed.
