[PATCH v4 26/29] arm: dts: ls1028a: disable the PCIe controller by default

[Michael Walle]

Disable the PCIe controllers by default, just like in the linux device
tree. But there is one catch, for linux they are enabled in-place by the
bootloader. Obviously, this doesn't work for the bootloader. Thus we
explicitly enable the controllers in the -u-boot.dtsi files.
