staging: mt7621-mmc: Start cleanup of msdc_dma_config

Browse source

Currently the msdc_dma_config function has some variables, that are
not needed, uses the macro msdc_init_bd that is only used here and
does not use the for_each_sg iterator. That last fact could cause a
bug if the scatterlist is chained.

The function is changed to remove these things, but none of the
changes should change the behavior of it (despite the case of a linked
scatterlist).
