Yes, that looks right.

The on-disk file was 'imx6q-sabrelite.dtb' when I received the board, I
replaced it with the one from the v4.1 kernel tree.

Decompiled from /sys/firmware/fdt (to eliminate bootloader trickery), the
pcie section reads:
pcie at 0x01000000 {
	compatible = "fsl,imx6q-pcie", "snps,dw-pcie";
	reg = <0x1ffc000 0x4000 0x1f00000 0x80000>;
	reg-names = "dbi", "config";
	#address-cells = <0x3>;
	#size-cells = <0x2>;
	device_type = "pci";
	ranges = <0x800 0x0 0x1f00000 0x1f00000 0x0 0x80000 0x81000000 0x0 0x0
0x1f80000 0x0 0x10000 0x82000000 0x0 0x1000000 0x1000000 0x0 0xf00000>;
	num-lanes = <0x1>;
	interrupts = <0x0 0x78 0x4>;
	interrupt-names = "msi";
	#interrupt-cells = <0x1>;
	interrupt-map-mask = <0x0 0x0 0x0 0x7>;
	interrupt-map = <0x0 0x0 0x0 0x1 0x1 0x0 0x7b 0x4 0x0 0x0 0x0 0x2 0x1 0x0

	clocks = <0x3 0x90 0x3 0xce 0x3 0xbd>;
	clock-names = "pcie", "pcie_bus", "pcie_phy";
	status = "okay";
