Add ECST tool to modify the header used by npcx booter.

Modified drivers:
1. i2c.c: Modify for i2c_port design.
2. i2c.c: Fixed bugs when mutil-tasks use the same i2c port and pull-up issue.
3. hwtimer.c: Fixed bug whcih event expired time is behide current timer.
4. lpc.c: Add intializing host settings after pltrst is deasserted.
5. uart.c/clock.c/register.h: Fixed bug which cannot enter deep-idle
   when gpio is any-edge trigger mode.
6. task.c: Add workaround method for hard fault issue.
7. keyboard_raw.c: Modified for support CONFIG_KEYBOARD_KSO_BASE
8. lpc.c: Modified for support CONFIG_KEYBOARD_IRQ_GPIO
9. lpc.c: fixed obe interrupt bug during 8042 initialization
10.Adjust path of flat files for new Makefile rules
11.Fixed build error on lpc.c without CONFIG_KEYBOARD_IRQ_GPIO

c3cd10937e WIP - Nuvoton 30-Jan patch
Issues fixed on 0216:
1.Modified CONFIG_KEYBOARD_COL2_INVERTED support in keyboard_raw.c
2.Modified warm_reset checking in gpio.c
3.Modified system_get_chip_name in system.c for package info.
4.Modified fan.c and pwm.c for:
● If the DCRn value is greater than the CTRn value, the PWM_n signal is always low.
● Fan stall condition event:
  If the measured fan speed is lower than the lowLimit value (unless the Fan Speed Low Limit value is 0) or in case of erroneous measurement, the userCallback is called.
5. Change cycle_pluses to 480 in board.c

Issues fixed:
1. Jump data at top of RAM is getting corrupted.  Changed the flag to
RESET_FLAG_RESET_PIN.  Added a workaround method to fix VCC1_RST
issue.

2. Hibernate wake need to report whether wake reason was GPIO or RTC

3. Hibernate wake must be distinguishable from watchdog reset.  The
booter will log reset reason in Code RAM.  I copy the log data to
battery-backup RAM in little FW.  And system driver will refer this
data to distinguish if it's watchdog reset or not.

4. Watchdog reset flag is not set.  Same fix as 3.

5. Should return error if unable to clear SPI flash status register.

6. Remove chip_temp_sensor.c

7. Remove use of pstate from flash driver

8. Remove support for watchdog warm reset

9. Keyboard raw driver must support COL2 inverted

10. LPC memory mapped data must be read-only from host

11. LPC should support PLTRST# signal

12. Problems reading chip type/version.  Use core registers and ROM data to read IDs.

13. When chip type/version is unknown, report hex value.

14. Watchdog does not consistently print panic information.

15. Remove console force enable logic.

16. Enable only the peripheral clocks that are needed.  Please notice
user should add bit mask in CGC_XXX_MASK if they want to enable
additional module.  For example, if user wants to enable PWM3, he must
add PWDWN_CTL2_PWM3_PD bit in CGC_PWM_MASK.

Please see HOOK_FREQ_CHANGE and HOOK_INIT these two hook functions.
If I turn off all I2C modules in system_pre_init and turn on the
modules I need in i2c_init, I found its freq is not correct.  The root
cause is hook_notify(HOOK_FREQ_CHANGE) is executed first (in
clock_init) before i2c_init.  At this time, i2c modules are power-down
and writing to freq register is useless.  I re-execute freq-changed
hook function after turning on modules again.

17. MPU properly configured to prevent code execution from data RAM

18. Partial nvcontext implementation.  Copy these 16 bytes in our battery-backup RAM.

Additional items we also modified:

1. pwm.c: Support open-drain IO type of PWM.  (PWM IO-Type cannot by
determined by GPIO, we use bit 1 & 2 of function byte of gpio_alt_func
array to support it)

2. ec_npcxflash.c: Use definition to replace constant value.  Stop
watchdog during flash programing.

3. npcx_cmds.tcl: Adjust script sequence for robustness.  Add unlock
MPU commands for Data RAM.
