Jens Wiklander e2af1cadf7 qemu: Add OP-TEE extra image parsing support
OP-TEE may have extra images to be loaded. Load them one by one and do
the parsing. In this patch, ARM TF need to load up to 3 images for
OP-TEE: header, pager and pages images. Header image is the info about
optee os and images. Pager image include pager code and data.  Paged
image include the paging parts using virtual memory.
