The device PM callback needs to be used only to suspend/resume devices. If the system cannot be suspended because UART is in a particular state, the pm_constraint_set/release API should be used. For NPCX UART, the chip can't enter low power idle state until UART completes the data transmission. This commit changes NPCX UART to use pm_constraint_set/release & fixes UART lost data from low power idle.
