From: Dinh Nguyen <dinguyen@altera.com>
It turns now that the only really platform specific code that is needed for
SOCFPGA is using the SDMMC_CMD_USE_HOLD_REG in the prepare_command function.
Since the Rockchip already has this functionality, re-use the code that is
already in dw_mmc-pltfm.c.

Like the rockchip, Altera's SOCFPGA platform specific implementation of the
dw_mmc driver requires using the HOLD register for SD commands. This patch
renames dw_mci_rockchip_prepare_command to dw_mci_pltfm_prepare_command so
that SOCFPGA and Rockchip can use it.

Introduce "altr,socfpga-dw-mshc" to enable Altera's SOCFPGA platform specific
implementation of the dwc_mmc driver.
Also add the "syscon" binding to the "altr,sys-mgr" node. The clock
driver can use the syscon driver to toggle the register for the SD/MMC
clock phase shift settings.
Finally, fix an indentation error for the sysmgr node.
