sunxi: Tune H3 DRAM PLL to improve lock time

The H3 PLL5 used for DRAM barely manages to lock to the required
frequency before DRAM controller starts, sometimes leading to wrong
delay-line calibration results.
This patch changes the PLL tuning parameters to the same values as
boot0 used, which speeds up the locking and fixes the problem.
