MLK-20945-1 imx8-power-domain: Check owned resource in power on 

When fspi is assigned to M4, we have to let the fspi probe failed when
its power domain is failed to power up. Because not all devices have power
domain (for example, external devices on the board). Current checking
resource owner in power domain probe is not good, change to check it in
power on.
