[PATCH] clocksource: Fix permissions for available_clocksource

[Heiko Carstens]

From: Heiko Carstens <heiko.carstens@xxxxxxxxxx>

File permissions for
/sys/devices/system/clocksource/clocksource0/available_clocksource
are 600 which allows write access. But this is in fact a read only
file. So change permissions to 400.
