This patch adds the support of the HS200 bus speed for eMMC 4.5 devices.
The eMMC 4.5 devices have support for 200MHz bus speed. The function
prototype of the tuning function is modified to handle the tuning command
number which is different in sd and mmc case.

I've minimally tested the platform version, but on the current mmc-next
I need the extra includes below. With these changes the patch looks
okay to me.
Note however that this patch will conflict with Jaehoon Chung's
dev_pm_ops patch, so it's probably worth fixing it to apply on top of
that once it

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.

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.

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.

This patch adds the support for predefined multiple block r/w.
dw_mmc can support MMC_CAP_CMD23 capability.

This patch adds caps2 filed for second capability in dw_mmc.
It corresponds with MMC_CAPS2_XXX. And this patch removes the
unnecessary condition statement for assigning caps.
