Subject: [RFC][PATCH 2/2] PM / Platform: Use generic runtime PM callbacks directly

From: Rafael J. Wysocki <rjw@...k.pl>

Once shmobile platforms have been converted to using power domains
for overriding the platform bus type's PM callbacks, it isn't
necessary to use the __weakly defined wrappers around the generinc
runtime PM callbacks in the platform bus type any more.
