hexagon: modify ffs() and fls() to return int

Browse Source 
Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a
printk format build warning.  This is due to hexagon's ffs() being
coded as returning long instead of int.

Fix the printk format warning by changing all of hexagon's ffs() and
fls() functions to return int instead of long.  The variables that
they return are already int instead of long.  This return type
matches the return type in <asm-generic/bitops/>.

../drivers/mtd/nand/raw/nandsim.c: In function 'init_nandsim':
../drivers/mtd/nand/raw/nandsim.c:760:2: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat]

There are no ffs() or fls() allmodconfig build errors after making this
change.
