soc: mediatek: fix the mistaken pointer accessed when subdomains are added

Browse Source 
commit 73ce2ce129783813e1ebc37d2c757fe5e0fab1ef upstream.

Fix the pointer to struct scp_subdomian not being moved forward
when each sub-domain is expected to be iteratively added through
pm_genpd_add_subdomain call.
