Display domain is removed due to instability issues. Explaining the problem below: exynos_init_late triggers the pm_genpd_poweroff_unused which powers off the unused power domains. This call hits before the trigger to deferred probes. DRM DP Panel defers the probe due to supply get failure. By the time, deferred probe is scheduled again, Display Power Domain is powered off by pm_genpd_poweroff_unused. FIMD and DP drivers are accessing registers during Probe and Bind callbacks. If display domain is enabled/disabled around register accesses, display domain gets unstable and we are getting Power Domain Disable fail notification. Increasing the Timeout also didn't help.
