Subject: [PATCH v4 14/24] clk: pwm: use pwm_get/set_default_xxx() helpers where appropriate

pwm_set/get_default_xxx() helpers have been introduced to differentiate
the default PWM states (those retrieved through DT, PWM lookup table or
statically assigned by the driver) and the current ones.
Make use of those helpers where appropriate.
