Freescale T4240QDS reference board has extra voltage shifters added
to allow 3.3V operation, so add 3.3v voltage support for T4240QDS.
1.8v and 3.3v is recommand for eMMC and SDHC card.

Vender version and sdhc spec version of T4240-R1.0-R2.0 is incorrect.
The right value should be VVN=0x13, SVN = 0x1. The wrong version number
will break down the ADMA data transfer. This defect only exist in
T4240-R1.0-R2.0.
Also share vvn and svr for public use.
