[media] include/media: split I2C headers from V4L2 core

Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.

Let's move those i2c specific files to its own subdirectory.

The files to move were produced via the following script:
	mkdir include/media/i2c
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done"
	);
    ) >script && . ./script

Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.
