pmdomain: core: fix unused variable warning with !PM_GENERIC_DOMAINS_OF

Browse Source 
The genpd provider bus is really only used when
CONFIG_PM_GENERIC_DOMAINS_OF is enabled, and since the recent deferred
initialisation of domain parent devices, the root device pointer is
otherwise unused.

Fix the unused variable warning by moving the definition of the root device
pointer inside the corresponding ifdef.
