staging: media: atomisp: add missing dependencies in Kconfig

Two dependencies were missing to build atomisp drivers:

_ MEDIA_CONTROLLER: to use the entity field of v4l2_subdev structure. Since
every atomisp driver needs MEDIA_CONTROLLER has a dependency, let's add it
to INTEL_ATOMISP

_ EFI: to use efivar_entry_get:
drivers/built-in.o: In function `gmin_get_config_var':
(.text+0xe062b): undefined reference to `efivar_entry_get'
