avr32: Use platform_driver_probe for pdc platform driver

The probe function of the pdc platform driver lives in the init section
and so a pdc device that is created after the init section is discarded
probably results in an oops.  Even if this cannot happen, using
platform_driver_probe is cleaner.  (If this can happen and should be
supported the probe function must live in the devinit section instead.)
