I suppose it should, as means to break devlink dependency, but I
personally haven't tried it yet.

It's easier to just have "msm" and "panel-*" modules in initramfs and
leave simpledrm node be with invalid scaling, because it doesn't live
long enough to display anything (maybe a fraction of a second) due to
being quickly replaced by msm drm framebuffer emulation.

Framebuffer-only display with proper scaling is only needed for devices
without display/panel drivers, perhaps temporarily during early porting
stage, so this all is minor issue.

Still would be nice to have a proper solution for this of course.
