Subject: omap hsmmc: fix a bug in card remove scenario
From: Madhusudhan Chikkature <madhu.cr@xxxxxx>
The reset of data lines when the card is removed from the cage results in
a failure.The failure is seen if the card is removed from the cage when TC
is pending after a CMD with data received CC.The reset logic leaves the
controller in a state where niether a TC is received nor DTO.
The rest code can be safely removed here since it is taken care in the IRQ
handler.
