sunxi: reduce Orange Pi Zero DRAM clock speed
Using `fel-boot-lima-memtester-on-orange-pi-pc 672` on an Orange Pi
without heatsink results in the following error after a few minutes:
WRITE FAILURE: 0x00200000 != 0xffdfffff at offset 0x0137f47c (bitflip).
Also, the constructor repository (github/orangepi-xunlong) seems to
contain that 624 Mhz clock speed in its u-boot fork. It may be that 672
Mhz is the advertized overclocked speed.
According to http://linux-sunxi.org/Orange_Pi_PC#DRAM_clock_speed_limit
it may be worth decreasing that value with other Orange Pi boards.
