compat-wireless: fix compile warning for wl12xx

Only CONFIG_WL12XX_SDIO and CONFIG_WL1251_SDIO are depending on
CONFIG_WL12XX_PLATFORM_DATA, so only these two config options should be
renamed. The other options should still use the normal name. The old
commit did not fix the problem for me.

This fixes compat-wireless commit:

        compat-wireless: fix compilation warning for wl12xx

Luis please add this into the linux-2.6.39.y branch.
