mediatek: filogic: disable eMMC HS400 mode for Mount Stuart series

The eMMC chip used in a small batch of these devices has issues operating
in HS400 mode. Reducing to HS200 mode works around the problem and does
not cause any noticeable performance penalties as smaller chips are not fast
enough to saturate the bus. Root cause analysis is pending.
