ARM: mach-shmobile: convert mackerel to use the generic MMC GPIO hotplug helper

Browse Source 
This also fixes the following modular mmc build failure:

arch/arm/mach-shmobile/built-in.o: In function `ag5evm_sdhi0_gpio_cd':
pfc-sh73a0.c:(.text+0x7c0): undefined reference to `mmc_detect_change'

on this platform by eliminating the use of an inline function, which
calls into the mmc core.
