This CL introduces a kernel device driver implemented by the internal 64/32-bit timers in Nuvoton NPCX series. Via these two kinds of timer, the driver provides an standard "system clock driver" interface. It includes: - A system timer based on an ITIM64 (Internal 64-bit timer) instance, clocked by APB2 which freq is CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC. - Its prescaler is set to 1 and provide the kernel cycles reading without handling overflow mechanism. - A event timer based on an ITIM32 (Internal 32-bit timer) instance, clocked by LCLK which frequency is 32KHz and still activated when ec entered "idle/deep idle" power state for better power consumption. - Its prescaler is set to 1 and provide timeout event mechansim. - Compensate system timer which clock is gating for better power consumption after ec left"idle/deep idle" power state. This CL passed starve, timer_api, and timer_monotonic test suites. Signed-off-by: Mulin Chao <mlchao@nuvoton.com>
