Whoops. Looks like I forgot to include the first patch of the series. Doh! I will
include it when I send v5.
The missing patch looks like this. Bjorn do you have any issues with adding this
interface?

Subject: [PATCH 01/19] remoteproc: add a rproc_get_elf_ops interface
This allows us to re-use some of the generic fw_ops such
as rproc_elf_sanity_check() and rproc_elf_load_segments() whilst
overriding some of the others with our own implementation.
