This serie add support for elf64 in remoteproc (elf loader, coredump).
First three patches modifies the type of len argument (in da_to_va),
boot_addr and rproc_mem_entry len field in order to allow loading elf64
segment with a u64 size and a u64 entry point.
Next patches introduce a set of macros to access elf64 and elf32
transparently.
Last patches are the actual modifications in the elf loader and
remoteproc coredump support to add elf64 support.

Changes v4 -> v5:
- Add rproc_elf_sanity_check renaming to rproc_elf32_sanity_check
- Fix checkpatch warning on > 80 column line
- Change u64 len type for size_t in da_to_va and add checks in loader
- Modify rproc_mem_entry size field type from int to size_t
- Add a patch to override sanity_check function

Changes v3 -> v4:
- Adapt coredump to elf64 file format
- Rename remoteproc_elf_loader.h to remoteproc_elf_helpers.h
- Update copyright year in remoteproc_elf_helpers.h
- Rename macros elf_hdr_* to elf_get_hdr_* for coherency with elf_hdr_set_*
- Split elf64 loader patch in 3:
- boot_addr u64 change
- remoteproc_elf_helpers.h creation
- elf64 loading

Changes v2 -> v3:
- da_to_va len type changed from int to u64
- Add check for elf64 header size
- Add comments for name table parsing
- Fix typo in "accommodate
- Add ELF64 support in documentation
