[PATCH 2/2] soc: amlogic: meson-ee-pwrc: propagate errors from pm_genpd_init()

[Martin Blumenstingl]

pm_genpd_init() can return an error. Propagate the error code to prevent
the driver from indicating that it successfully probed while there were
errors during pm_genpd_init().

Fixes: eef3c2ba0a42a6 ("soc: amlogic: Add support for Everything-Else power domains controller")
