ARM: mach-shmobile: convert ag5evm to use the generic MMC GPIO hotplug helper
This also fixes the following modular mmc build failure: arch/arm/mach-shmobile/built-in.o: In function `mackerel_sdhi0_gpio_cd': pfc-sh7372.c:(.text+0x1138): undefined reference to `mmc_detect_change' on this platform by eliminating the use of an inline function, which calls into the mmc core.
