The existing loops were iterating through all RAM_CONFIGS, but
they must only iterate over those that match the RAM size on the
platform's UBOOT_CONFIG.
This commit adds a Python class 'boot-artifacts' to get the list of matching
combinations of RAM_CONFIGS and UBOOT_CONFIG so that the iteration
is easier to do than nesting loops inside one another.
