rk3288: sdram: auto-detect the capacity
Add support for rk3288 dram capacity auto detect, support DDR3 and LPDDR3, DDR2 is not supported. The program will automatically detect: - channel number - rank number - column address number - row address number
The dts file do not need to describe those info after apply this patch.

sunxi: Add support for SID e-fuses on sun9i
The A80 has SID e-fuses. Like other newer SoCs, the actual e-fuses are at an offset of 0x200 within the SID address space.

sunxi: add gtbus-initialisation for sun9i
On sun9i, the GTBUS manages transaction priority and bandwidth for multiple read ports when accessing DRAM. The initialisation mirrors the settings from Allwinner's boot0 for now, even though this may not be optimal for all applications (e.g. headless systems might want to give priority to IO modules).
Adding a common callout to gtbus_init() from the SPL clock init with a weakly defined implementation in sunxi/clock.c to fallback to for platforms that don't require this.

sunxi: DRAM initialisation for sun9i
This adds DRAM initialisation code for sun9i, which calculates the appropriate timings based on timing information for the supplied DDR3 bin and the clock speeds used.
With this DRAM setup, we have verified DDR3 clocks of up to 792MHz (i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.
