Some improvements for some boards' DRAM setup, to allow boards with
"odd" DRAM sizes (1.5GB or 3GB), and to support the T113-s4 with double
the co-packaged DRAM. Support for a new board (X96Q TV box), and a fix
for the DT name prefix. Also we support the new AXP318W PMIC, which is
used on new boards with the A733 SoC. There are some preliminary support
patches for this SoC, but they are not quite ready yet - though maybe I
push some uncontroversial ones a bit later still.
