[PATCH 10/10] arm: mvebu: clearfog: don't assume MMC booting

[Joel Johnson]

Remove MMC booting assumptions from clearfog_defconfig. Their
presence in starting config files conflicts with default ENV_IS_IN
selection logic based on boot source, since the "select" option
can't distinguish between user-overridden and defconfig selected.

The real objective is to remove CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC as
well but I couldn't identify an available mechanism to do so.
Requiring it as enabled in the defconfig results in additional items
being unneccessarily included if switching boot device after starting
with the defconfig, as well as ENV_IS_IN_MMC being undesirably
residually defined.
