This is right. Bindings documentation is wrong. :) And I will put the prefix as "dts" on subject, according to your other comment.

Add the Exxynos5433 pcie node for TM2. This pcie device is used for supporting WiFi. And some gpios are already requested from pinctrl. so it doesn't need to initialize. GPJ2-0 is used for supplying to WiFi PCIe chip.
