sunxi: dram: Optionally use standard JEDEC timings for sun[457]i In addition to the current Android magic settings, allow to optionally use DDR3 timing parameters, which are tailored for different clock frequencies and JEDEC speed bins. This should improve reliability and performance. Adding '+S:CONFIG_DRAM_TIMINGS_DDR3_1066F_1333H=y' to the board defconfig allows to use timings, which are calculated for the DDR3-1066F speed bin. A lot of DDR3 chips, which are used in real Allwinner based devices, support DDR3-1066F speed bin timings. And adding '+S:CONFIG_DRAM_TIMINGS_DDR3_800E_1066G_1333J=y' should work with any DDR3 chips, because this targets the slowest JEDEC speed bins. The vendor magic values are still used by default for DRAM, but board maintainers now have more flexibility in DRAM timings selection.
