driver: uart: npcx: Fix CR_SIN interrupt storm NPCX WIMU CR_SIN is used to wake up soc from NPCX sleep power state. The wake-up IRQ enabled when UART init. It causes the wake-up IRQ to generate many extra interrupt events, which causes the system too busy to handle other events. This PR moves the UART wake-up IRQ enabling from UART init to npcx_power_enter_system_sleep() to avoid the interrupt storm. Signed-off-by: Wealian Liao <WHLIAO@nuvoton.com>
