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.

The 'of_pwm_n_cells' has been removed from the pwm_chip structure in the
latest linux-next development branch that will eventually become Linux
v6.9. This parameter was used in function 'of_pwm_xlate_with_flags'.
The camera CDI and ISC drivers don't use the kernel's
of_pwm_xlate_with_flags xlate function and instead implement their own
xlate function. Therefore, it is safe to simply drop the usage of the
'of_pwm_n_cells' parameter completely in these drivers.

Commit 54c86dd20bba ("pwm: Replace PWM chip unique base by unique ID")
removed the 'base' field of the 'pwm_chip' structure replacing it with
an 'id' field. The new 'id' is initialised by the PWM driver core and
does not need to be configured by the PWM drivers.
Add a test for conftest to detect if the 'pwm_chip' structure has the
'base' field and update the various PWM driver to only set this field if
present.
