google/snow: Minor clean-ups for display setup code in ramstage
This just cleans up a few areas:
- Removed an unnecessary delay from exynos_dp_bridge_setup()
- The delay at the end of exynos_dp_bridge_init() is necessary, so
removed the comment suggesting that it might not be.
- Simplified exynos_dp_hotplug
