[PATCH] mmc: dw_mmc: modified the DMA threshold for SD card

[Jaehoon Chung <jh80.chung@samsung.com>]

This patch modified the DMA threshold.

I didn't know exactly why need this threshold.
But if this value is 16, we didn't read SCR register for SD card.
Because in mmc_app_send_scr this values are used data.blocks=1 and data.blksz=8.
(data.blocks * data.blksz = 8...so return -EINVAL)

We didn't read the SCR register, then maybe should be set with wrong configuration.
