[PATCH 1/2] bloblist: fix the overriding of fdt from bloblist

[Raymond Mao]

When a bloblist is valid and contains fdt, it explicitly means
a previous boot stage is passing transfer list compliant with
Firmware Handoff specification, thus the fdt from bloblist should
not be overridden with the ones from board or env variables.

Fixes: 70fe23859437 ("fdt: Allow the devicetree to come from a bloblist")
