Subject: PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on()

From: "Rafael J. Wysocki" <[email protected]>

commit 57d13370cfaf6017c68981e66ff5b3bf20a2705c upstream.

Make the MTU2 clocksource driver mark its device as "always on"
using pm_genpd_dev_always_on() to protect it from surprise power
removals.
