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_pdc202xx_old) has been available
since 2006 and it supports all the hardware supported by the old
pdc202xx_old host driver.
Remove the deprecated pdc202xx_old host driver.

- This driver adds up to 4 more EIDE devices sharing a single
- interrupt. This add-on card is a bootable PCI UDMA controller. Since
- multiple cards can be installed and there are BIOS ROM problems that
- happen if the BIOS revisions of all installed cards (three-max) do
- not match, the driver attempts to do dynamic tuning of the chipset
- at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
- for more than one card.
