ramips: Fix sdhci kernel panics on MT7621

Enable work-arounds present in the code commented-out but needed to write to
sdcard on mt7621 which currently causes kernel to oops when engaging in
serious writing to sdcard. With this change applied, there are still
occasional warnings thrown by the mmc driver, however, at least it no longer
crashes the system and even large writes (full-card dump/erase/write/compare)
don't show any corruption.

Rebase to LEDE and added "CONFIG_SOC_MT7621" check to ensure non-MT7621 devices do not face performance regressions.
