fastboot/recovery: wait for display
With GKI we find in certain situations the timing of the drivers
loading is delayed as compared to a monolithic kernel. This
introduces a race where during second stage init, the attributes
inside /sys/bus/platform/drivers/drm_dsi_ctrl might not be set by
the time the menu is painted on the screen.
To address this, we wait for /sys/class/drm/card0 to instantiate.
