The STOP command can terminate a data transfer between a memory card and
mmc controller.

As show in Synopsys DesignWare Cores Mobile Stroage Host Databook:
s/Stroage/Storage but maybe Ulf can amend the typo when applying?

Data timeout and Data end-bit error will terminate further data transfer
by mmc controller. So we should not send abort command to terminate a
data transfer again if we got DRTO and EBE interrupt.

After this patch, all mmc_test cases can pass on RK3288-Pink2 board.

I did not run all the tests listed in /sys/kernel/debug/mmc*/*/testlist
because some of them will overwrite the data in my card but at least
the read ones completed successfully and $subject does not cause a
regression in the Exynos5250 Snow, Exynos5420 Peach Pit and Exynos5800
Peach Pi Chromebooks where I tested it.
