Add NAND secure boot target for ls1043ardb. - Change the u-boot size defined by a macro for copying the main U-Boot by SPL to also include the u-boot Secure Boot header size as header is appended to u-boot image. So header will also be copied from SD to DDR. - MACRO for CONFIG_BOOTSCRIPT_COPY_RAM is enabled to copy Bootscript from NAND to DDR. Offsets for Bootscript on NAND and DDR have been also defined.
