drivers: pwm: add pwm driver support in NPCX7 series In npcx7 series, there're 8 Pulse Width Modulator (PWM) modules and each one support generating a single 16-bit PWM output. A 16-bit clock prescaler (PRSCn) and a 16-bit counter (CTRn) determine the cycle time, the minimal possible pulse width, and the duty-cycle steps. Beside introducing pwm driver for Nuvoton NPCX series, this CL also includes: 1. Add PWM device tree declarations. 2. Zephyr PWM api implementation. 3. Add aliases in npcx7m6fb_evb board device tree file for supporting samples/basic/blinky_pwm application and pwm test suites Signed-off-by: Mulin Chao <MLChao@nuvoton.com>

depends on SOC_FAMILY_NPCX
help
This option enables the PWM driver for NPCX family of
processors.
Say y if you wish to use pwm ports on NPCX MCU.
