The Rockchip DMC (Dynamic Memory Interface) needs to access to the PMU
general register files to know the DRAM type, so add a phandle to the
syscon that manages these registers.

DDR3 SDRAM Standard (JESD79-3F) defines some standard speed bins for
DDR3 memories. The rk3399_dmc driver allows you to pass these values via
the device tree. For that purpose the devfreq/rk3399_dmc.txt binding
refers to a ddr.h file which does not exist. This patch adds the missing
defines in a include file called rk3399-ddr.h with the definition of
standard speed bins according to the ARM Trusted Firmware (ATF).

Compiling the DT file with W=1, DTC warns like follows:
Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property
Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.
