From: Jerry Huang <chang-ming.hu...@freescale.com>
When access the card on some FSL platform board (e.g p2020, p1010, mpc8536),
the following error is reported with the timeout value calculated:
mmc0: Got data interrupt 0x00000020 even though no data operation was
in progress.
mmc0: Got data interrupt 0x00000020 even though no data operation was
in progress.
So we skip the calculation of timeout and use the max value to fix it.
