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
