[PATCH 2/5 v2] ESDHC: set the timeout to the max value

[<r66093@freescale.com>]

From: Jerry Huang <Chang-Ming.Huang@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.
