[PATCH] staging: media: atomisp: use str_on_off() helper

[Giorgi Tchankvetadze]

Replace the ternary operator with str_on_off() for printing
"on"/"off" strings. This improves readability and follows the
kernel's preferred style. Also add the required header
<linux/string_choices.h> to provide the helper.
