ARM: imx: gpc: Initialize all power domains
Since commit 0159ec670763dd ("PM / Domains: Verify the PM domain is present when adding a provider") the following regression is observed on imx6: imx-gpc: probe of 20dc000.gpc failed with error -22 The gpc probe fails because of_genpd_add_provider_onecell() now checks if all the domains are initialized via pm_genpd_present() function and it fails because not all the power domains are initialized. In order to fix this error, initialize all the power domains from imx_gpc_domains[], not only the imx6q_pu_domain.base one.
