The function was defined as taking 4 parameters and returning EFI_STATUS, but all existing callers (in asm code) passed only two parameters and don't use the return value. The function signature now matches that usage, and doesn't refer to efi-specific types. Parameters and variables now use the cannonical typenames set up by elf.h (Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will prevent suprises as new platforms come along and use this code. The function was renamed from _reloc() to self_reloc() to emphasize its difference from the other elf relocation code found in boot/common. Differential Revision: https://reviews.freebsd.org/D2490
