drivers: pwm: Fix build for Linux v6.8

Browse Source 
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.
