Subject[42/75] ARM: 7214/1: mmc: mmci: Fixup handling of MCI_STARTBITERR
3.1-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Ulf Hansson <ulf.hansson@stericsson.com>

commit b63038d6f4ca5d1849ce01d9fc5bb9cb426dec73 upstream.

The interrupt was previously enabled and then correctly cleared.
Now we also handle it correctly.
