As incredible as it sounds, some people run neither "git status" nor
"git diff" every few minutes and not even when their build fails. There
has been reports that they're puzzled when they miss a required
submodule update. This is an attempt to draw their attention based on
the assumption that they pay more attention to the CMake logs.

- Add a simple test in cmake to download submodules only when rimage is
missing. This stops randomly changing the source code from one build
to the next and overwriting any submodule work in progress.
- Remove the GIT_SUBMODULE option which is now useless because rimage is
not optional for sof
- Add a --merge option for safety. It makes zero difference right now
but could save work in progress if we ever add more
submodules (hopefully not) and someone struggles with submodules and
ends up in a partially initialized state.
Git submodules are rarely ever the answer; these few changes make them a
bit more usable.

This adds the necessary bits to update git submodules when
cmake is run, with the option to turn this behavior off if
needed. This is in preparation to use fw.h and manifest.h
from the rimage repo to prevent having two copies of each
file in two different repos. Obviously, the files in
the submodules must exist before building the firmware,
so run git submodule update to checkout the files.
