MLK-20945-2 dm: device: Check the power up result in probe
If a device has relevant power domain, we will check the power up
result in probing the device. If the power up is failed, the device_probe
will return failure immediately.
The only exception is the new FLAG (DM_FLAG_IGNORE_POWER_ON) is set by driver
to indicate ignore the power up result.
