Subject: [PATCH] mmc: dw_mmc: fix timeout calculate method

There are two cases not been considered:
- use uint for timeout, it will overflow when size bigger than 512KB for
   it *8*1000 at the beginning, but we may use size up to 32MB;
- The timeout is using clock speed for data rate, but the device may not
   have such high speed, eg. clock is 52MHz while the device write speed
may
   be less than 10MB/s.

Fix them in this patch, the max timeout is about 6500 when size is
32MB after fix.

This patch breaks build, I need drop it.
See build:
https://travis-ci.org/MrVan/u-boot/jobs/577210464
The error happens only in ARC architecture, and seems like the arc 
compiler not support

64bit div?

Any idea on how to fix this?


Thanks,

Applied to mmc/master.
