ARM: EXYNOS: Add __init attribute to universal_camera_init()

s3c_set_platdata() is defined with __init attribute, hence all functions
referencing this function should also be defined with __init attribute.

universal_camera_init() is referenced only in '__init universal_machine_init()',
thus this change won't put any additional constraint on the usage of
universal_camera_init().
