The DDRTYPE defines are named to be RK3399 specific, but they can be used for other Rockchip SoCs as well, so replace the RK3399_PMUGRF_ prefix with ROCKCHIP_. They are defined in a SoC specific header file, so when generalizing the prefix also move the new defines to a SoC agnostic header file. While at it use GENMASK to define the DDRTYPE bitfield and give it a name including the full register name.
