Final patch to broken AVR arch with the latest gdbs

This patch obsoletes all previous patches attached to this bug.
The patch is trivial and only affects avr-tdep.c.
As noted by others, avr_integer_to_address() always returns addresses in SRAM.
However, the second parameter of this function, struct type *type, allows to
understand if a code or data address is desired.

Indeed, patch is so simple that the patched function is simply:

static CORE_ADDR
avr_integer_to_address (struct gdbarch *gdbarch,
                        struct type *type, const gdb_byte *buf)
{
  ULONGEST addr = unpack_long (type, buf);

  if (TYPE_DATA_SPACE (type))
    return avr_make_saddr (addr);
  else
    return avr_make_iaddr (addr);
}

Everything works: disassemble, breakpoints at numeric address, breakpoints at
source line and watchpoints.
