ARM: shmobile: pm-rmobile: Use GENPD_FLAG_ALWAYS_ON 



Improve handling of always-on PM domains by using the
GENPD_FLAG_ALWAYS_ON flag introduced in commit ffaa42e8 ("PM /
Domains: Enable users of genpd to specify always on PM domains").

Note that the PM domain containing the serial console is still handled
locally.
