pmdomain: bcm: bcm2835: handle genpd provider registration errors

Browse Source 
bcm2835_power_probe() initializes all power domains and then registers
the onecell genpd provider, but ignores of_genpd_add_provider_onecell()
failures. Probe can therefore return success even though no provider was
published.

Check the provider registration return value and jump to the existing
cleanup path on failure.
