[PATCH v3] scripts: socfpga_import_preloader: Translate DOS line endings

[Ian Abbott]

If the handoff files were generated on a Windows system, they will have
DOS line endings (CRLF).  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 `dos2unix` command to `copy_source()` to change the DOS
line endings (CRLF) to Unix line endings (LF).

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

v2: Corrected tabs in echoed output.
v3: Use dos2unix instead of sed, as suggested by Ahmed Fatoum.  Remove
    the corresponding echo command because dos2unix is verbose enough
    already!
