interconnect: qcom: rpm: fix registration race
commit
90ae93d8affc1061cd87ca8ddd9a838c7d31a158 upstream.
The current interconnect provider registration interface is inherently
racy as nodes are not added until the after adding the provider. This
can specifically cause racing DT lookups to fail.
Switch to using the new API where the provider is not registered until
after it has been fully initialised.
