Convert various device_get_binding to DEVICE_DT_GET, which is processed
at link time and more efficient. Same pattern on different modules where
the output is checked using device_is_ready.

Adjusts the watchdog warning timer value and its delay time definitions
to meet original chromium ec behavior. The system handles the warning
event at CONFIG_AUX_TIMER_PERIOD_MS & issues the watchdog reset event
at CONFIG_WATCHDOG_PERIOD_MS.
Zephyr NPCX watchdog provides a config WDT_NPCX_DELAY_CYCLES for
watchdog timeout delay. Set the zephyr timeout to
CONFIG_AUX_TIMER_PERIOD_MS as warning time. So the NPCX watchdog
hardware issue reset event at CONFIG_AUX_TIMER_PERIOD_MS +
WDT_NPCX_DELAY_CYCLES.

In npcx7 series, the Timer and Watchdog module (TWD) generates the
clocks and interrupts used for timing periodic functions in the system.
It also provides watchdog reset signal generation in response to a
failure detection. This CL enables the watchdog functionality in zephyr
system.
