According to the card detection of p1/p2 paltform RM,
typo => platform
we should set SYSCTL[PEREN] to enable the clock.
Otherwise, after booting the u-boot, and then inserting the SD card,
the SD card can't be detected.

If I read the iMX6 manual correctly, the SYSCTL_PEREN isn't implemented
there. So this should be a NOP for iMX6?
