core: Add subid to load_resource()
This adds a subid to load_resource() so that sub-partitions can be accessed
inside a PNOR partition. These sub-partitions follow the format used by the
hostboot SBE image.
The subid will match on the EC field of the SBE table of contents. If it's
found, only that sub-partition is returned to the caller.
Current partitions (kernel and ramfs) don't support sub-partitions. If caller
tries to access a sub-partition within these, we fail the call.
