Subject: [RFT][PATCH 2/3] arm64: dts: exynos: fix WLAN pin configuration in TM2

Each pin configuration in pin controller should be a node with
"samsung,pins" and other similar properties.  However the macro PIN()
(used for initial/sleep states) defines entire node, so PCIe WLAN pin
configuration node was ignored.
