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_it8213) has been available since
2006 and it supports all the hardware supported by the old
it8213 host driver.
Remove the deprecated it8213 host driver.
