platform: add a platform hook for loading external resources
Currently, in core/init.c we do a fsp-specific load procedure to grab
the kernel image.
We'd like to do two things: allow other types of resources, and have
paths for non-FSP platforms to perform loads.
This change adds a platform-specific load_resource hook, and moves the
currently loading code to fsp_load_resource. To allow other resource
types, we add an identifier to indicate the type of resouce to load.
