[PATCH v1 1/3] ram: starfive: drop references to 16GB memory size

[E Shattow]

16GB memory size is not addressable on StarFive JH-7110 SoC because the
DRAM uncached alias begins at +8GB offset from start of DRAM. The logic
for 16GB memory size is a fall-through to the default for an unknown size.
Let's drop this unnecessary 16GB memory size and rely on the case default.
