Modified hibernate funcs to support hibernate_wake_pins on weatley, npcx_evb and npcx_evb_arm. For better power consumption, we disable ADC, tri-state spi pins, all inputs of wake-ups to prevent leakage current caused by input floating and set necessary GPIOs' states in hibernate function. Modified drivers: 1. npcx_evb/board.c: Add hibernate_wake_pins array for hibernate. 2. npcx_evb_arm/board.c: : Add hibernate_wake_pins array for hibernate. 3. wheatley/board.c: Add hibernate_wake_pins array for hibernate. 4. wheatley/board.c: Add board_set_gpio_state_hibernate func for adjusting GPIOs' status related to board for better power consumption. 5. hwtimer.c: Remove unnecessary interrupt_enable/disable funcs. Interrupt will disable before it is called. 6. register.h: Add WKINEN definition and declarations used for hibernate. 7. system.c: Add system_set_gpios_and_wakeup_inputs_hibernate to set GPIOs' state and wake-up inputs before entering hibernate. 8. system_chip.h: Remove unused BBRM_DATA_INDEX_PBUTTON field. 9. gpio.c: Enable WKINEN in gpio_set_flags_by_mask func.
