I'm working on the GRUB port to ARM using the EFI platform. When
generating a relocatable ARM image, some relocation entries use a
relocation code (0x33) which is not defined in include/grub/elf.h. So I
went through the latest edition of the ELF specification for the ARM
architecture (ARM IHI 0044E) and added the missing definitions to the
header file. I also noticed some differences between the existing
definitions and the spec: some relocation names are different from the
spec, some definitions aren't in the spec at all, and one
(R_ARM_IRELATIVE) has a different value than that from the spec. So
while at it I fixed those differences as well. Hence this patch.

* include/grub/elf.h: Add missing ARM relocation codes and fix
existing ones.
