[PATCH 1/2] ARM: dts: imx6sx-sdb: Disable PCI support

From: Fabio Estevam <fabio.estevam at nxp.com>

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.
