Now CONFIG_GENERIC_MMC and CONFIG_MMC match for all defconfig. We do not need two options for the same feature. Deprecate the former. This commit was generated with the sed script 's/GENERIC_MMC/MMC/' and manual fixup of drivers/mmc/Kconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
