To better support different RAM timings (DDR3-1333 and DDR3-1866 are assembly options for the RK3399-Q7), this refactors the DTS support and renames the default DTS variant from rk3399-puma to rk3399-puma-ddr1600:
- changes the rk3399-puma DTS into a board-specific DTSI by removing the inclusion of the DRAM timings
- adds a new rk3399-puma-ddr1600.dts, which includes the (new) common board DTSI and the DDR3-1600 timing DTSI
- wires this up from arch/arm/dts/Makefile and configs/puma-rk3399_defconfig

Changes in v2:
- changed implementation from Kconfig and C preprocessor macros in the DTS to using one DTS per DRAM timing that contains only two includes: one for the common board-level definitions and one for the DRAM timings
