SD card read was failing (data crc error)on some cards at
maximum possible frequency on P1010(CCB frequency set to 400MHz).
Some clock deviations are also observed at this frequency.
Hence reduced the mmc clock freq.

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 0x0020 even though no data operation was
in progress.

For FSL ESDHC controllor, when enter the sleep, the controller will power off,
therefore the register will lost its valuse, and driver should save value of
register during suspend and used during resume.

For some FSL ESDHC controller(e.g. P2020E, Rev1.0), the SDHC can not work on
DMA mode because of the hardware bug, so we set a broken dma flag and use
PIO mode.
