Subject: [PATCH] media: atomisp: Do not define input_system_cfg2400_t twice

When CONFIG_VIDEO_ATOMISP_ISP2401 is disabled, clang warns:

./drivers/staging/media/atomisp//pci/isp2400_input_system_local.h:32:40:
error: redefinition of typedef 'input_system_cfg2400_t' is a C11 feature
[-Werror,-Wtypedef-redefinition]
typedef struct input_system_cfg2400_s           input_system_cfg2400_t;
                                                ^
./drivers/staging/media/atomisp//pci/input_system_local.h:22:40: note:
previous definition is here
typedef struct input_system_cfg2400_s           input_system_cfg2400_t;
                                                ^
1 error generated.

input_system_cfg2400_t's typedef was copied from
isp2400_input_system_local.h to input_system_local.h, rather than moved.
Remove the one in isp2400_input_system_local.h so that there is no more
warning, which can break the build under -Werror.
