media: camera: Use of_pwm_xlate_with_flags()

Browse Source 
In Linux v6.11, commit d6f66e292676 ("pwm: Make pwm_request_from_chip()
private to the core") made the function pwm_request_from_chip() a
private function to the PWM core driver. This function is used by both
the CDI and ISC camera drivers and so these driver no longer build
against Linux v6.11.

Fix this by updating the CDI and ISC drivers to use the function
of_pwm_xlate_with_flags() which has been supported since Linux v3.8.
This function internally calls pwm_request_from_chip() and configures
the pwm->args.period parameter and is therefore, equivalent to the
existing code.
