media: ov08x40: Move ov08x40_identify_module() function up

[ Upstream commit 7a39639e448f070cbe37317ac922886b6080ff43 ]

Move the ov08x40_identify_module() function to above ov08x40_set_stream()
this is a preparation patch for adding a missing ov08x40_identify_module()
call to ov08x40_set_stream().

No functional changes, just moving code around.
