Subject: [PATCH] ths7303: Declare as static a private function

git grep shows that the function is only called from ths7303.c

Fix this build warning:

CC      drivers/media/i2c/ths7303.o
drivers/media/i2c/ths7303.c:86:5: warning: no previous prototype for  ‘ths7303_setval’ [-Wmissing-prototypes]
   int ths7303_setval(struct v4l2_subdev *sd, enum ths7303_filter_mode mode)
        ^
