media: v4l: use WARN_ON(1) instead of __WARN()
__WARN() cannot be used in portable code, since it is only
available on some architectures and configurations:
drivers/media/platform/pxa_camera.c: In function 'pxa_mbus_config_compatible':
drivers/media/platform/pxa_camera.c:642:3: error: implicit declaration of function '__WARN'; did you mean '__WALL'? [-Werror=implicit-function-declaration]
The common way to express an unconditional warning is WARN_ON(1),
so let's use that here.
Fixes: 97bbdf02d905 ("media: v4l: Add support for CSI-1 and CCP2 busses")
