Set up interrupts correctly so that Linux can use all devices. Use savedefconfig to regenerate the defconfig file.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v4: - Use the same interrupt routing as bayleybay
Changes in v3: - Drop unnecessary blank lines - Add PCIe root ports from bayleybay
Changes in v2: - Use pirq_init() instead of custom code
