bfd: remove use of PTR

* coffcode.h (coff_write_object_contents): Don't cast to PTR.
	* elf32-csky.c (csky_elf_link_hash_traverse): Remove use of PTR
	and PARAMS.
	(csky_allocate_dynrelocs): Don't use PTR cast.
	* elf32-nios2.c (adjust_dynrelocs, allocate_dynrelocs): Replace
	PTR with void *.
	* elf32-visium.c (visium_elf_howto_parity_reloc): Likewise.
	* elfxx-ia64.c (ia64_elf_reloc): Likewise.
	* plugin.c (bfd_plugin_bfd_print_private_bfd_data): Likewise.
