Enable support for the CW1200 connected via an SDIO bus.
+ By default this driver only supports the Sagrad SG901-1091/1098 EVK
+ and similar designs that utilize a hardware reset circuit. To
+ support different CW1200 SDIO designs you will need to override
+ the default platform data by calling cw1200_sdio_set_platform_data()
+ in your board setup file.
