Subject: [PATCH 1/2] scripts/make_fit: Drop fdt image entry compatible string

According to the FIT image spec, the compatible string in the fdt image
node or any image node specifies the method to load the image, not the
compatible string embedded in the FDT or used for matching.

Drop the compatible string from the fdt image entry node.

While at it also fix up a typo in the document section of output_dtb.

Fixes: 7a23b027ec17 ("arm64: boot: Support Flat Image Tree")
