Introduces state management and debugging mechanisms for the MediaTek ISP7.x camsys platform. State management establishes control over ISP operations and events, defining distinct states for request handling, sensor control, and frame synchronization, ensuring event processing. The debugging mechanism ensures stable operation and timely data collection during anomalies. Signed-off-by: Shu-hsiang Yang <redacted> ---

CAMSYS_IRQ_FRAME_DROP is never set, so drop it. Regards, CK
