cleanup sweep:
  - Kill ps3fb_priv.xdr_ea and ps3fb_priv.xdr_size, use info->screen_base and
    info->fix.smem_len instead.
  - Kill superfluous assignments to info->fix.smem_start, info->fix.smem_len,
    and info->screen_base in ps3fb_set_par(). Their values never change.
  - Add sparse annotations to casts to kill address space warnings
