[PATCH 1/2] sunxi: H616: dram: fix LPDDR3 TPR6 parsing

[Philippe Simons]

From: Jernej Skrabec <jernej.skrabec at gmail.com>

When a user copies the vendor value of tpr6 into the mainline U-Boot,
the code parses the tpr6 parameter incorrectly and writes the wrong value.
Fixes Vref parsing from TPR6. Proper order from LSB to MSB is DDR3, DDR4,
LPDDR3 and LPDDR4

Fix that.
