Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.

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

Add callback function sdhci_get_cd to detect the card.
And one new callback added to implement the card detect in sdhci struncture.
If special platform has the card detect callback, it will return the card

The commit 05f5799 (mmc-host: move to dma_transfer_direction) left out
the DMA_NONE, in turn breaks the driver as below.

The driver gpmi-nand should compile at least. This patch adds the
missing gpmi-nand.h to fix the compile error below.

Before dma_transfer_direction was introduced to replace
dma_data_direction, some dmaengine device uses DMA_NONE of
dma_data_direction for some talk with its client drivers.
The mxs-dma and its clients mxs-mmc and gpmi-nand are such case.
This patch adds DMA_TRANS_NONE to dma_transfer_direction and
I have been working on -rc recently, and have not noticed the failure
until I ran next tree today. The mxs-mmc driver is broken on next
tree because the DMA_NONE was left over from the dma_transfer_direction
migration for mxs-dma and its client drivers.
This seires is trying to fix it up.
