spl: Remake SPL elf from bin
On Xilinx MB-V there is a need to use ELF file for SPL which is placed
in BRAM (Block RAM) because tools for placing code to bitstream requires to
use ELF. That's why introduce SPL_REMAKE_ELF similar to REMAKE_ELF option
as was originally done by commit f4dc714aaa2d ("arm64: Turn u-boot.bin back
into an ELF file after relocate-rela").
There is already generic and simple linker script (arch/u-boot-elf.lds)
which can be also used without any modification.
