[PATCH v3 1/2] sunxi: H616: dram: fix LPDDR3 TPR6 parsing

[Andre Przywara]

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

Allwinner's DRAM initialisation code defines a parameter named TPR6,
presumably containing some "Vref" parameter, but containing values for
*all* DRAM types. The runtime code selects one byte based on the DRAM
type used.
This selection code was wrong for LPDDR3, the value is encoded in
bits [23:16], not [15:8]. Fix that in the code, which also aligns it
with the very similar code for the A133 and A523.
