[PATCH] scripts: socfpga_import_preloader: Translate DOS line endings

[Ian Abbott <abbotti@mev.co.uk>]

If the handoff files were generated on a Windows system, they will have
DOS line endings.  The `indent` program (with the options used by the
script) does a lousy job tidying up those files, leaving ASCII CR
characters embedded in the lines.  This is particularly bad for array
initializers that have one value per line, because they all end up on a
single line with embedded ASCII CR characters between each value.

Add an initial `sed` command to `copy_source()` to match and remove an
ASCII CR character from the end of each input line.

Also output a message before running `unifdef` and fix the spelling of
"paths" in one of the other messages.
