Greetings,

Here is a bunch of trivial and mostly boring stuff we want to do before
pushing the RISC-V Server Plat Reference board upstream (currently on
v9 [1], not yet sent for review).

Although these changes aim to ease the pain for the riscv-server-ref
review, in the end virt.c was reduced from ~1800 to ~1200 lines, which
is a nice benefit we can have right now.  For riscv-server-ref we went
from ~1450 (v8) to ~770 lines (current v9).

We were able to also reduce tt-atlantis code in one of the patches too.
In fact I think there are opportunities to shrink tt-atlantis board
size, but that will need refactoring logic here and there and this would
fall out of scope for this work.

Patches based on master.
