nuc: Support hibernate_wake_pins on wheatley, npcx_evb and npcx_evb_arm.
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.
