Change parse_fw callback in rproc ops from qcom_register_dump_segments
to rproc_elf_load_rsc_table, as section header to be parsed for memory
sandboxing required platforms.

This is sad.

Why not have two different set of ops so that the function pointer table
can't be hijacked? One for the parse_fw callback? Or simply return from
rproc_elf_load_rsc_table() when has_iommu is false?
