As a preparation for turning the SDIO side of wilc1000 into a separate module, this removes the last direct caller from the core module into the sdio specific portion. All calls to wilc_sdio_enable_interrupt() and wilc_sdio_disable_interrupt() now go through a function pointer in wilc_hif_func. We also change arguments slightly to pass the device, as we are already touching those lines and the change will be needed later to remove the global variables.
