K2G devices still only use single parameter for power-domains property,
so check for this properly in the driver. Without this, every peripheral
fails to probe resulting in boot failure.

Fixes: efa5c01cd7ee ("soc: ti: ti_sci_pm_domains: switch to use multiple genpds instead of one")

Can you please add this to your fixes queue ?
