[PATCH v3 2/2] riscv: dts: starfive: generate u-boot-spl.bin.normal.out

[Heinrich Schuchardt]

The StarFive VisionFive 2 board cannot load spl/u-boot-spl.bin but needs a
prefixed header. We have referring to a vendor tool (spl_tool) for this
task. 'mkimage -T sfspl' can generate the prefixed file.

Use binman to invoke mkimage for the generation of file
spl/u-boot-spl.bin.normal.out.

Update the documentation.

v3:
	Rename binman node for SPL image.
	Use u-boot-spl instead of blob as mkimage subnode.
v2:
	Fix a typo in a comment in tools/sfspl.c
	Add Tested-by credits
