Current DWMMC driver used to give FIFO underrun/overrun error every 3rd time for mmc rescan command. In current code FIFO_DEPTH is getting calculated after reading the default FIFOTH register and extracting the RX_WMARK bits from it i.e (RX_WMARK = FIFO_DEPTH/2 -1). Instead of storing the correct value, we were recalculating the FIFO_DEPT each time which is not correct.

Looks like the patch this is based on is already accepted, but not yet upstream, so I'm going to delegate the patch to Minkyu Kang
