media: atomisp: Remove struct atomisp_platform_data
struct atomisp_platform_data only has a single subdevs member. Remove
this struct and replace atomisp_get_platform_data() with
atomisp_platform_get_subdevs().
Note atomisp_get_platform_data() and now atomisp_platform_get_subdevs()
always succeed, so while at it also remove unnecessary error checking.
