cpuidle: psci: Fix regression leading to no genpd governor 

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2067314

commit 34be27517cb763ea367da21e3cdee5d1bc40f47f
Author: Ulf Hansson <ulf.hansson@linaro.org>
Date:   Sat May 14 17:20:32 2022 +0200

While factoring out the PM domain related code from PSCI domain driver into
a set of library functions, a regression when initializing the genpds got
introduced. More precisely, we fail to assign a genpd governor, so let's
fix this.
