Ouch, thanks for that. I missed to delete the above quirk from
sdhci_esdhc_imx_pdata. Can you give another try removing it?

That should prevent polling. Fixed here already. Will wait for Eric's
tests and send a v3 then.

MX51 won't need platform data. The pins can be routed to the controller,
like efika-mx51 does (judging from the source and documentation).
