[PATCH 2/2] remoteproc: add support to handle internal memories

A remote processor may need to load certain firmware sections into internal memories (eg: RAM at L1 or L2 levels) for performance or other reasons. Introduce a new resource type (RSC_INTMEM) and add an associated handler function to handle such memories. The handler creates a kernel mapping for
