arm64: dts: marvell: samsung,coreprimevelte: Use memory-region for framebuffer

Browse Source 
Since the framebuffer resides in system RAM, use the memory-region
property preferred in that case over reg.

Also, testing showed that reusing most of the region (excluding where
the actual framebuffer resides) is perfectly safe, so do that and save
~22.5 MiB of RAM in the process.
