	Set the dram controller tpr3 parameter. This parameter configures
	the delay on the command lane and also phase shifts, which are

	granularity is 1/4 cycle. For example, the value 0x05060606
	means that the delay is 5 quarter-cycles for one lane (1.25
	cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
	The default value 0 means autodetection. The results of hardware
	autodetection are not very reliable and depend on the chip
	temperature (sometimes producing different results on cold start
	and warm reboot). But the accuracy of hardware autodetection
	is usually good enough, unless running at really high DRAM
	clocks speeds (up to 600MHz). If unsure, keep as 0.

	used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
	or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
	that down binning to DDR3-1066F is supported (because DDR3-1066F
