Versal can also have reserved space in DT which u-boot has to avoid to placing self to that location. The same change was done in ZynqMP by commit ce39ee28ec31 ("zynqmp: Do not place u-boot to reserved memory location") and also for microblaze by commit d7b5cc89d329 ("microblaze: Do not place u-boot to reserved memory location").

The patch was tested by adding reserved-memory node to DT and check via bdinfo back.
