Added the parsing for APPEND_EXTRA_CMDS variable, which enables the
user to specify the path to a text file that contains, on each line,
u-boot commands that will be added to the generated script as
"fixups", before the boot command.
The file specified by the APPEND_EXTRA_CMDS variable parameter will be
copied as-is in the generated script.
