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.
