[PATCH] MPBL0010 driver sysfs permissions wide open 

The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone
can write) permissions on its writable sysfs entries.  Alter the
permissions to 0220 (owner and group can write).

The use case for this driver is to configure the fail over behavior of the
clock hardware.  That should be done by the more privileged users.
