drm_hwcomposer: Fall back to client compositon if the gl precompostior fails
If the gl precompositor isn't being used, we cannot accept
every layer as a device composited layer.
Thus this patch adds some extra logic in the validate function
to fall back to client side compositing if the gl precompositor
did not initialize properly.
This does force everything to a single plane even if we have
a few available, but a deeper rework of the validate step
planning is needed before we can reliably make use of them.
Credit to Rob Herring, who's single plane patch was what this
was originally based on.
