Makefile: Simplify calculation of region base with default fmd files
When using default fmd files, base of the fmap region is currently calculated based on the size and base of previous fmap regions. Since the existence of any fmap region is dependent on the selection of certain CONFIG_* parameters, these calculations get complicated. Every time base is calculated for a region, there need to be checks to see which of the previous regions really exist. As the regions in default fmd file are increased, these calculations and the conditional checks get even more complicated.
This change introduces a Makefile variable FMAP_CURRENT_BASE which is updated every time a new region is allocated space. This allows using the same steps for determining the base of any fmap region irrespective of the state of previous regions.
The way the code is organized it should be possible in the future to also add a macro to perform the same steps (in case that is possible).
TEST=Verified that coreboot image generated remains unchanged for x86 and ARM boards using the default fmd files.
