soc: fsl: qe: properly scan GPIO nodes at startup
Before commit 156460811def ("soc: fsl: qe: Change GPIO driver to a
proper platform driver") qe_add_gpiochips() was walking the device
tree to find all nodes with compatible "fsl,mpc8323-qe-pario-bank".
After that commit the discovery is handled by the platform core,
therefore it is necessary to call of_platform_default_populate() on
the par_io node.
Fixes: 156460811def ("soc: fsl: qe: Change GPIO driver to a proper platform driver")
