The gpa1-4 pin was put twice in UART3 pin configuration of Exynos5250,
instead of proper pin gpa1-5.

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.

This patch is not correct, because the driver/bindings allow and work
with such DTS. Please ignore.

Well, the uart3_data node is not referenced anywhere, so this change is 
not really relevant to any board, but for the completeness, feel free to 
add:
