On arm64, board info is not applicable and kernel command line patched into the DT, so the LMB reservation here makes no sense anymore. On legacy arm32, this might still be necessary on systems which do not use DT or use legacy ATAGS. Disable this LMB reservation on arm64.
This also permits Linux DT to specify reserved memory node at address close to the end of DRAM bank, i.e. overlaping with U-Boot location. Since after boot, U-Boot will be no more, this is OK.
