ARM: 6980/1: mmci: use StartBitErr to detect bad connections

Stresstesting insert/remove of SD-cards can trigger
a StartBitErr. This made the driver to hang in forever
waiting for a non ocurring data timeout.

This bit and interrupt is documented in the original
PL180 TRM, just never implemented until now.
