IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.
The replacement driver (pata_sis) has been available since
2006 and it supports all the hardware supported by the old
sis5513 host driver. Also x86 defconfigs have switched to
use libata PATA exclusively in 2008.
Remove the deprecated sis5513 host driver.

- * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original
- * SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511
- * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
- *
- * Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
- * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
- * can figure out that we have a more modern and more capable 5513 by looking
- * for the respective NorthBridge IDs.
- *
- * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
- * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
- * ID, while the now ATA-133 capable 5513 still has the same PCI ID.
- * Fortunately the 5513 can be 'unmasked' by fiddling with some config space
- * bits, changing its device id to the true one - 5517 for 961 and 5518 for
- * 962/963.
