[COMMON] pwm: samsung: support 0% and 100% duty cycle
PWM generates a pulse within a specific period repeatedly.
However, some drivers require duty cycle 0% or 100% to PWM. This
patch supports them on S3C64XX and EXYNOS series only. It does not
support them on S3C24XX series.
100% duty cycle: TCMPB >= TCNTB, invert set
0% duty cycle: clear auto-reload
