[PATCH] image/image-live: Add back IMAGE_TYPES_MASKED support

[Richard Purdie <richard.purdie@linuxfoundation.org>]

IMAGE_TYPES_MASKED support was accidentally removed. The original 
idea behind it was to remove some of the hardcoding in the core 
image code, so do that for image-live and ensure the dependency 
and masked variables correctly reflect the needs of the class. 
This means we can remove all the hardcoded special cases since 
image-vm already has the needed markup.
