fastboot: mmc: Add CONFIG_FASTBOOT_MMC_USER_SUPPORT

Browse Source 
Split userdata and boot partition support for eMMC update
and correct the description (update is supported).

The new configuration CONFIG_FASTBOOT_MMC_USER_SUPPORT
allows to activate support of userdata partition update,
based on target name=CONFIG_FASTBOOT_MMC_USER_NAME

This patch also removes the unnecessary dependency with
ARCH_MEDIATEK and EFI_PARTITION.
