This patch marks w9968cf_valid_depth as inline, although it's used
before it's defined.

gcc 3.4 therefore correctly fails with:

<--  snip  -->

...
  CC      drivers/usb/media/w9968cf.o
drivers/usb/media/w9968cf.c: In function `w9968cf_set_picture':
drivers/usb/media/w9968cf.c:487: sorry, unimplemented: inlining failed
in call to 'w9968cf_valid_depth': function body not available
drivers/usb/media/w9968cf.c:1722: sorry, unimplemented: called from here
make[3]: *** [drivers/usb/media/w9968cf.o] Error 1

<--  snip  -->


This patch moves w9968cf_valid_depth above it's first user (it also uses
two other functions to keep the ordering of functions a bit more
consistent).
