omap: remove patch wlcore Add-support-for-DT-platform-data

- does not compile with 3.18
compile error: 'struct wl12xx_platform_data' has no member named 'gpio'

- different version was sent 2015 but cannot be tested by me
see "[PATCH v7 0/6] wlcore: add device-tree support" series
in linux-omap

-When running with DT, we no longer have a board file that can set up the
-platform data for wlcore. Allow this data to be passed from DT.
-
-Since some platforms use a gpio-irq, add support for passing either the
-irq number or the gpio number. For the latter case, the driver will
-request the gpio and convert it to the irq number. If an irq is
-specified, it'll be used as is.
-
-[Arik - the pdev_data pointer does not belong to us and is freed when
-the device is released. Dereference to our private data first.]
