When support for EN7581 was introduced, it was assumed to follow the MT7531 model. However, on Airoha EN7581 and AN7583 switch IP, setting MT7531_CFC alone is not sufficient for trapped control frames (such as STP BPDUs) to exit towards the CPU port. The switch forwarding hardware also requires the MT7530_CPU_EN bit and MT7530_CPU_PORT field to be enabled in MT753X_MFC (0x10). Without this, trapped frames are dropped by the switch forwarding logic and never reach the CPU conduit. Include ID_EN7581 and ID_AN7583 in mt753x_conduit_state_change() to set MT7530_CPU_EN and MT7530_CPU_PORT in MT753X_MFC when the conduit becomes operational, matching the handling for MT7530, MT7621, and EN7528.
