arm64: dts: socfpga: Add clk-phase-sd-hs property to the sdmmc node
The sdmmc controller's CIU(Card Interface Unit) clock's phase can be
adjusted through the register in the system manager. Add the binding
"altr,sysmgr-syscon" to the SDMMC node for the driver to access the
system manager. Add the "clk-phase-sd-hs" property in the SDMMC node to
designate the smpsel and drvsel properties for the CIU clock.
