sunxi: dram: Remove useless 'dramc_scan_dll_para()' function

The attempt to do DRAM parameters calibration in 'dramc_scan_dll_para()'
function by trying different DLL adjustments and using the hardware
DQS gate training result as a feedback is a great source of inspiration,
but it just can't work properly the way it is implemented now. The fatal
problem of this implementation is that the DQS gating window can be
successfully found for almost every DLL delay adjustment setup that
gets tried. Thus making it unable to see any real difference between
'good' and 'bad' settings.

Also this code was supposed to be only activated by setting the highest
bit in the 'dram_tpr3' variable of the 'dram_para' struct (per-board
dram configuration). But none of the linux-sunxi devices has ever used
it for real. Basically, this code is just a dead weight.
