[U-Boot] [PATCH] qts-filter.sh: strip DOS line endings and handle continuation lines

[Bill Randle]

Some Altera Quartus generated files have long lines that are split with a '\' at
the end of the line. It also writes files in DOS format, which can confuse some
of the processing scripts in this file. This patch solves both issues.
