imx: ventana: default pci to disabled
The IMX6 PCIe host controller does not have a proper reset and as such there are several issues that can arise if PCI is enabled in the bootloader follwed by Linux trying to re-configure LTSSM and/or toggling PERST# to the devices. For now, the best approach seems to default to disabling PCI by defaulting pciedisable=1. This can be overridden by the user if they need PCI in the bootloader, for example: - GW552x needing ethernet access in bootloader - GW16082 expansion board needing a device-tree fixup for irq mapping Signed-off-by: Tim Harvey <tharvey@gateworks.com>
