DDR Bandwidth Bottleneck and Device Tree Errors

The Orange Pi 5 device tree has 65 errors and 1,223 violations, with a significant issue being the estimated peak DDR bandwidth at 128% of the theoretical limit. This causes performance issues such as audio glitches and frame drops under heavy NPU load. The errors include unresolved power-domain phandles and high-bandwidth peripherals saturation.
