[PATCHv9 2/4] dts: socfpga: Add support for SD/MMC on the SOCFPGA platform

[dinguyen at altera.com]

From: Dinh Nguyen <dinguyen at altera.com>

Use the "snps,dw-mshc" binding to enable the dw_mmc driver.
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.

v9: none
v8: none
v7: Use the standard "snps,dw-mshc" binding. Remove "altr,socfpga-sdmmc-sdr-clk".
v6: Add documentation for "altr,socfpga-sdmmc-sdr-clk". Add "syscon" to the
sysmgr binding.
v5: Use the "snps,dw-mshc" binding
v4: Re-use "rockchip,rk2928-dw-mshc" binding
v3: none
v2: none
