The commit 284ef1bbcefc ("doc: memory: Add documentation for system
RAM") added documentation for U-Boot's memory usage along with diagrams
showcasing the SPL's memory usage. Although the SVGs for the diagrams
were improperly encoded.

Therefore, this patch fixes the older SVGs with one's with better
encoding and reduced size created using inkscape[1].

When applying the patch that became commit a2d881f5bcd3 ("doc: memory:
Add documentation for system RAM") one of the diagrams was missed.
Re-add this missing file.
