Subject: [PATCH] arm: dts: fsl-ls1088a: match Linux FDT by disabling PCIe by
default
The Linux kernel fsl-ls1088a.dtsi disables (status="disabled")
all PCIe controllers by default, with the bootloader (i.e U-Boot)
enabling the appropriate controllers (specified by the board
reset control word/RCW) by FDT fixup.
However, U-Boot needs these controllers to be enabled
to be usable, which we can add in the u-boot only dtsi.
