Nicolas Boichat c27ca99e28 soc: mediatek: Check if power domains can be powered on at boot time
[ Upstream commit 4007844b05815717f522c7ea9914e24ad0ff6c79 ]

In the error case, where a power domain cannot be powered on
successfully at boot time (in mtk_register_power_domains),
pm_genpd_init would still be called with is_off=false, and the
system would later try to disable the power domain again, triggering
warnings as disabled clocks are disabled again (and other potential
issues).

Also print a warning splat in that case, as this should never
happen.
