mmc: tmio: enhance illegal sequence handling
An illegal sequence command error may occur if there is a stopbit or
cmd_index error as well as a CRC error. The correct course of action
is to re-enable IRQs
An illegal sequence data error may occur if there is a CRC or stopbit
error, or underrun. In this case set data->error correctly.
This is in preparation for enabling tuning support which relies on
differentiating between illegal sequence and other errors.
