The IPQ5210 boot ROM expects the SPL binary image to be embedded within
an ELF along with additional binaries. Hence add the relevant commands
and linker script needed to convert u-boot-spl.bin to the expected
format.

v4: Use $(obj) for u-boot-spl.wrap-elf
v3: s/a image/an image/
Add SPDX header to linker script
Pre-process linker script to use IMAGE_TEXT_BASE instead of hard coding it
