ARM: PCI: add legacy IDE IRQ implementation
The IDE code used to specify the IDE IRQs for chipsets operating in legacy mode. This appears to no longer work, and this information must be provided by the arch. Do so. This partially fixes CY82C693 (and probably others) on Footbridge platforms. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
