Samuel Dionne-Riel a9368b3623 splash: review "loading"...
While it's not as useful as the other splashes, this may help showing
issues with early post-framebuffer init. E.g. network or adbd in
stage-1.

The hollow logo is simple to describe, compared to a black and white
one, compared to a full colour one.
