There were some files in the code base with multiple inclusion of the same header files.
Following changes are made to mitigate this issue.

 1) --check-dup-head option is added to the scripts/clean-includes to search files and
    find out such entries. This will help to catch redundant #includes in the future.
 2) Removed most of the duplicate entries currently present in the code base using the 
    script.

Added script to check duplicate #include entries. This check will scan
and print the files in which duplicate #include entries are present.

Script might output false positive entries as well. Such entries should
not be removed. So if it finds any duplicate entries script will
terminate with an exit status 1. Then each and every file should be
checked manually and corrected if necessary.

In order to enable the check use --check-dup-head option with
scripts/clean-includes.

Some files contain multiple #includes of the same header file.
Removed most of those unnecessary duplicate entries using
scripts/clean-includes.

You didn't actually add a script, but enhanced an existing one.  Also,
"Added" is past tense, but commit messages are best written in
imperative tense.  Better might be:

Enhance the clean-includes script to optionally check for duplicate
#include entries.

(But be careful of line wraps; git eats lines starting with # if the
wrap happens at the wrong place while editing your message)

Includes can be indented.  It is valid to write:
 #include ...
or
# include ...
or even
 # include ...

(of those three, we most commonly use the style:
# include ...
to delineate includes inside an #if conditional).

So a better expression might be grep "# *include" "$@", which may in
turn find more duplicates; on the other hand, those duplicates are more
likely to be conditionals where the duplication is necessary (see for
exampel include/qemu/bswap.h vs. <sys/endian.h>).  Then again, if you
allow whitespace in your grep, you have to remove that whitespace before
passing things to sort and uniq, if you want a fair comparison that
finds two duplicate includes that differ only by whitespace.
