[PATCH 1/2] soc: imx: gpc: ARM power domain should be always-on

[Anson.Huang@nxp.com (Anson Huang)]

ARM power domain does NOT support runtime off, always-on
flag should be set to avoid incorrect power state in
pm_genpd_summary:

Before:

root at imx6qpdlsolox:~# cat /sys/kernel/debug/pm_genpd/pm_genpd_summary
domain                          status          slaves
    /device                                             runtime status
----------------------------------------------------------------------
ARM                             off-0

After:

root at imx6qpdlsolox:~# cat /sys/kernel/debug/pm_genpd/pm_genpd_summary
domain                          status          slaves
    /device                                             runtime status
----------------------------------------------------------------------
ARM                             on
