[PATCH v2 13/13] ARM: s3c24xx: camif: include header with prototypes and unify declaration

[Krzysztof Kozlowski <krzk@kernel.org>]

The s3c_camif_gpio_put() declaration in
include/media/drv-intf/s3c_camif.h header was different than definition.
Fixing this allows to include that header to also fix the W=1 compile
warnings:

    arch/arm/mach-s3c24xx/setup-camif.c:28:5: warning: no previous prototype for 's3c_camif_gpio_get' [-Wmissing-prototypes]
       28 | int s3c_camif_gpio_get(void)
    arch/arm/mach-s3c24xx/setup-camif.c:56:6: warning: no previous prototype for 's3c_camif_gpio_put' [-Wmissing-prototypes]
       56 | void s3c_camif_gpio_put(void)
