[PATCH v3] media: rc: pwm-ir-tx: Switch to atomic PWM API

[Maíra Canal <maira.canal@xxxxxx>]

Remove legacy PWM interface (pwm_config, pwm_enable, pwm_disable) and
replace it for the atomic PWM API.

Signed-off-by: Maíra Canal <maira.canal@xxxxxx>

V1 -> V2: Assign variables directly and simplify conditional statement
V2 -> V3: Fix declaration of undeclared variable
