sparc: copy sparc64 specific files to asm-sparc

Used the following script to copy the files:
cd include
set -e
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
	if [ -f asm-sparc/$FILE ]; then
		echo $FILE exist in asm-sparc
	else
		git mv asm-sparc64/$FILE asm-sparc/$FILE
		printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
		git add asm-sparc64/$FILE
	fi
done
