interconnect: exynos: fix registration race
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 trigger a NULL-pointer deference when either a NULL pointer or not fully initialised node is returned from exynos_generic_icc_xlate().
Switch to using the new API where the provider is not registered until after it has been fully initialised.
