ARM: dts: imx6sx-sdb: Disable PCI support

From: Fabio Estevam <[email protected]>

When I added PCI support for this board I was testing with mainline U-Boot, which has PCI support and enables the i.mx6sx PCI power domain.

When running on a U-Boot without PCI support, such as the one provided by NXP a kernel hang is observed.

Better to disable the pci node for now, until the i.MX6SX PCI power domain is properly implemented in the kernel.

Hi Shawn,

Just sent two patches that add i.MX6SX PCI power domain support.

If they are accepted then this one can be discarded.

Patch 2/2 of this series should still be applied though.

Thanks

The third cell of the PCI non-prefetchable memory range should be 0x08000000, so change it accordingly.

Applied this one, thanks.
