[PATCH v3 2/8] binman: allow user-defined filenames for mkimage entry

[Quentin Schulz]

From: Quentin Schulz <quentin.sch...@theobroma-systems.com>

mkimage entry currently creates a file whose name is derived from the
section name containing said entry.

Let's allow the user to define a filename for the mkimage-generated
binary by using the 'filename' DT property.
