RFA: Fix compile time warnings building iq2000-tdep.c

[Nick Clifton <nickc@redhat.com>]

Hi Guys,

  The iq2000 port of GDB currently fails to build on the 6.6 branch
  and mainline because of compile time warnings triggered in
  iq2000-tdep.c, (which are now being treated as errors).  The
  patch below fixes them by changing various void* variables into
  gdb_byte*.

  May I apply the patch please ? 

Cheers
  Nick Clifton

	gdb_byte*.
	(iq2000_address_to_pointer): Likewise.
	(iq2000_frame_prev_register): Likewise.
	(iq2000_extract_return_value): Change type of return_buffer to
	gdb_byte.
	(iq2000_return_value): Change type of readbuf and writebuf to
