[media] s5p-fimc: fix compiler warning

drivers/media/platform/s5p-fimc/fimc-m2m.c:561:2: warning: passing argument 2 of 'fimc_m2m_try_crop' discards 'const' qualifier from pointer target type [enabled by default]
drivers/media/platform/s5p-fimc/fimc-m2m.c:502:12: note: expected 'struct v4l2_crop *' but argument is of type 'const struct v4l2_crop *'
This is fall-out from this commit:
commit 4f996594ceaf6c3f9bc42b40c40b0f7f87b79c86
