This commit fixes the MMC data transactions timeout problem on the
TS4800.
The changes introduced in the commit e978a31 on the timeout calculation
for the MMC data transactions has revealed there is something wrong with
the timeout setting of the eSDHC controller used in the IMX51.
The IMX51 seems to be concerned by this erratum and without this change
the MMC driver is unable to do any transactions.
