PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on()
Make the MTU2 clocksource driver mark its device as "always on" using pm_genpd_dev_always_on() to protect it from surprise power removals. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Tested-by: Simon Horman <horms@verge.net.au> Acked-by: Paul Mundt <lethal@linux-sh.org> Cc: stable@vger.kernel.org
