pbio/platform/ev3/platform.ld: Remove DDR_unused (#367)

ArcaneNibble · web-flow · commit ea811e14618e · 2025-08-05T17:08:49.000-05:00
This reclaims the memory and makes it available for use. Previously,
we needed to reserve this space for the uImage file that was being
used but now we use a .elf file so we don't need to reserve any space
for the uImage header.
