Some Bay Trail systems:
- Use a non CR version of the Bay Trail SoC
- Contain at least 6 interrupt resources so that the platform_get_resource(pdev, IORESOURCE_IRQ, 5) check to workaround non CR systems which list their IPC IRQ at index 0 despite being non CR does not work
- Despite 1. and 2. still have their IPC IRQ at index 0 rather then 5
Add a DMI quirk table to check for the few known models with this issue, so that the right IPC IRQ index is used on these systems.
