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_cs5535) has been available since 2006 and it supports all the hardware supported by the old cs5535 host driver. Also x86 defconfigs have switched to use libata PATA exclusively in 2008. Remove the deprecated cs5535 host driver.
