or1k: Implement relocation R_OR1K_GOT_AHI16 for gotha()
The gotha() relocation mnemonic will be outputted by OpenRISC GCC when
using the -mcmodel=large option. This relocation is used along with
got() to generate 32-bit GOT offsets. This increases the previous GOT
offset limit from the previous 16-bit (64K) limit.
This is needed on large binaries where the GOT grows larger than 64k.
bfd/ChangeLog:

* bfd-in2.h: Add BFD_RELOC_OR1K_GOT_AHI16 relocation.
* elf32-or1k.c (or1k_elf_howto_table, or1k_reloc_map): Likewise.
(or1k_final_link_relocate, or1k_elf_relocate_section,
or1k_elf_check_relocs): Likewise.
* libbfd.h (bfd_reloc_code_real_names): Likewise.
