[PATCH] image_types.bbclass: get rid of IMAGE_DEPENDS

[Ed Bartosh <ed.bartosh@linux.intel.com>]

The IMAGE_DEPENDS variable can be overriden to add dependencies for
individual image types.  Those dependencies are added to the do_rootfs
task, while they really should be added to the specific image type tasks.

Also, the IMAGE_DEPENDS variable is not documented anywhere.

Replaced usage of IMAGE_DEPENDS with explicitly added
dependencies to do_image_<image type> tasks.

[YOCTO #11302]
