Currently if a platform wants to implement a non-standard card-detection method, it would need to call tmio_mmc_cd_wakeup(), which is an inline function, calling mmc_detect_change(). For this the platform would have to link mmc_core statically into the kernel, losing the ability to build it as a module. This patch adds a callback to the sh_mobile_sdhi driver, which eliminates this dependency.
