Right now we use fixed indexes to assign power-domains, with a
requirement for the TOP GDSC to come last in the list.
Adding support for named power-domains means the declaration in the dtsi
can come in any order.
After this change we continue to support the old indexing - if a SoC
resource declration or the in-use dtb doesn't declare power-domain names
we fall back to the default legacy indexing.
From this point on though new SoC additions should contain named
power-domains, eventually we will drop support for legacy indexing.

Unnecessary, I think

No need to nullcheck, dev_pm_domain_attach_by_name seems to return
NULL when the name is NULL
It looks so. Then again I'm sure checking here saves a few instructions
and stack operations..
