soc: imx: gpc: fix domain_index sanity check issue
ARRAY_SIZE(imx_gpc_domains) represents all power domains supported
by different SoCs. Driver should use SoC specific of_id_data->num_domains
instead to do power domain index sanity check.
e.g. MX6Q supports two power domains while MX6SL supports three.
