imx: power-domain: Descend into pgc subnode if present
In case the power domain node structure is gpc@303a0000/pgc/power-domain@N,
do not bind power domain driver to the 'pgc' node, but rather descend into
it and only bind power domain drivers to power-domain@N subnodes. This way
we do not waste one useless driver instance associated with 'pgc' node.
