Subject: [PATCH] sunxi: Fix H616 DRAM read calibration for dual rank
Although it isn't known what bit 0 in PHY reg 8 does, it's obvious that
it has to be set before read calibration and cleared afterwards. This is
already done for first rank, but not for second (copy & paste error.)
Fix it.
Fixes: f4317dbd06b6 ("sunxi: Add H616 DRAM support")
