[PATCH v2 1/8] mmc: mtk-sd: select LMB_LIMIT_DMA_BELOW_RAM_TOP

[David Lechner]

Default to CONFIG_LMB_LIMIT_DMA_BELOW_RAM_TOP=y when CONFIG_MTK_SD is
enabled. The MediaTek SD controller can only access the first 4GB of RAM
when DMA is used. "imply" is used rather than "select" in case someone
want's to turn off the option when DMA is not used.
