Subject: [PATCH v2 5/5] wlcore: move wl12xx_platform_data up and make it truly optional
The platform data is used not only by wlcore-based drivers, but also
by wl1251. Move it up in the directory hierarchy to reflect this.
Additionally, make it truly optional. At the moment, disabling
platform data while wl1251_sdio or wlcore_sdio are enabled doesn't
work, but it will be necessary when device tree support is
implemented.

In v2:
* Fix ti/Makefile
* Modify board_omap3evm.c which was still using the old Kconfig define
Tony, is it okay if I add this change in the omap3evm board in this
patch and queue it via wireless so that the whole thing is in sync?
